I. INTRODUCTION
Unity has been developed under the umbrella of Unity-
Technologies that is a cross-platform game engine released
in 2005 June at World Wide Apple Inc’s Conference as an
exclusive game engine (Mac OS X). In 2018, the engine was
extended and facilitated more than 20 platforms. This game
engine can be used to develop the augmented reality, virtual
reality, two-dimensional, and three-dimensional, games
along with simulations and for other practices. This game
engine in the 21st Century has been adopted by businesses
outside video gaming like film, architecture, automotive,
construction, and engineering [1]. This paper is presenting
survey on the Unity as in the current epoch amid the IT
(Information Technology) sector the surge of gaming and its
development has emerged enormously; however, Unity is
playing actively in game development and thus, the
researchers of this paper deem that there must be some
comprehensive survey that supports the people working in IT
sector to connect with the benefits, challenges, and
appropriate solutions of those challenges that emerged in the
Unity. This ultimately helps the readers and the people allied
with the IT sector in the development of relevant knowledge
and understanding of Unity.

has been conducted. The documentation of relevant works
and examination of the collected sources fundamentally is
demonstrated in Fig 1. Moreover, Fig 1 is constructed with
the help of a technique named as PRISMA, depicted below.
Therefore, the literature review has been considered as one of
the vital aspects of the research paper as its supports authors
as well the readers in understanding and examining several

facets that the relevant to the current topic and are conducted
previously.
Figure 1. PRISMA Chart
Unity, a multi-platform game engine, commercially
available and is used for 2d and 3D video games production
accompanied by visualizations and non-game interactive
simulations. Moreover, Unity is one of the popular engines
for games that is easily accessible, and in the current epoch is
communal amid the developers due to its ease, flexibility,
efficiency, and power consumption. Multiple tools have been
featured in the Unity Editor that permits rapid iteration and
editing in the cycles of development comprised of smart
previews play mode in real-time [2]. Furthermore, Unity is
offered on Mac, Linux, and Windows it contains an artist-
friendly range of tools for immersive designing and game
worlds, in addition to a strong developer tools suite for
implementing high-performance gameplay and game logic
[3]. Moreover, Unity supports 3D and 2D development with
functionalities and features for the specific needs that are
further focused on categories.
Similarly, [4] has quoted that the navigation system has
also been included in Unity that permits to create NPCs that
logically move around the world of gaming [28]. navigation
meshes have been used in the system that is automatically
created from the scene geometry, or sometimes even from the
dynamic obstacles, to change the character's navigation at
runtime. Unity Prefabs that are known as the pre-configured
objects of gaming provide the workflow flexibility and
efficiency that permit in the confident working without
nerve-wracking about the time-consuming errors [5].
According to [6] it has been found that Unity built-in UI
system permits to create the UI intuitively and smartly with
less consumption of time. Unity takes Box2D advantage the
novel DOTS-based NVIDIA PhysX and Physics system that
aids in the provision of high-performance and high realistic
gameplay. Developers can extend the Editor of Unity with
tools need to match the workflow of teams. It also supports
the creation and customizing of the extensions that feature
many possessions, extensions, and tools for the sake of
speediness of the projects [29].
According to [2] one of the feature highlights of this
discharge for Android is the accessibility of a seen form of
Adaptive Performance for Samsung Galaxy leads. In contrast
to PC and consoles, gaming on cell phones characteristically
impediment of warmth the board and power utilization.
Lovely looking and smooth-messing around have escalated
handling needs, which can rapidly warm up your gadget. PC
and consoles handle this issue through their dynamic cooling
frameworks, yet since telephones don't include dynamic
cooling equipment (yet), the telephone winds up throttling
execution to hold the temperature within proper limits. The
issue turns out to be much progressively risky considering the
wide scope of equipment accessible, and the shifting
execution and throttling situations. In addition, some of the
key features of unity are related to the simple workflow that
allows developers to quickly combine scenes in a workspace
referred to as (intuitive editor). It also supports creating high-
quality games like AAA images, high definition sound, and
action at full speed with no gaps on the screen [32]. Also,
some extra features are [33] access the components, coroutine
and return types, creating and destroying GameObjects,
dealing with vector variables and timing variables, events for
GameObject, and physics-oriented events. Primarily, Unity
supports scripting in C#, and there are two ways to design C#
scripts in Unity: object-oriented design, which is the more
traditional and widely used approach, and data-oriented
design, which is now possible in Unity [34].
Moreover, according to [1] game designers handle this
issue through two fundamental methodologies: guaranteeing
the most extreme similarity by giving up realistic loyalty and
casing rate, or by foreseeing equipment conduct, which is
hard to execute. Solidarity and Samsung have teamed up for
a component called "Versatile Performance", which gives a
superior method to oversee thermals and execution of games
continuously. After you introduce Adaptive Performance
through the Unity Package Manager, Unity will consequently
add the Samsung GameSDK subsystem to your undertaking.
During runtime and on upheld gadgets [7]. Unity will make
and begin an Adaptive Performance Manager which will give
criticism about the warm condition of the gadget [30].
Engineers would then be able to decide to buy into
occasions or inquiry the data from the Adaptive Performance
Manager during runtime to make responses progressively
concerning warm patterns. For example, when the gadget
started throttling in the beginning periods, the game could
tune quality settings, target outline rate, and different
parameters to guarantee that the game can squeeze out
increasingly continued execution. When the temperature

University of Sindh Journal of Information and Communication Technology (USJICT) Vol.4(2), pg.: 73-81
75
begins declining once more, parameters could be changed by
and by to convey better ongoing interaction execution. By
watching out for the warm presentation, one can abstain from
throttling all together by modifying execution dependent on
constant criticism. This will prompt a gradual unsurprising
edge rate and interactivity experience and lower warm
buildup [1, 2, 8].
Therefore, based on the studies examined in the literature
review, a conceptual framework is formulated exposed below
(See Fig 2). Hence, this supports the readers in analysing the
gap that may have a reflection on delineating the concept of
the proposed paper.

III. METHODOLOGY
Qualitative research methodology has been adopted in this
paper in which the data is gathered from already available
researches available in the form of peer-reviewed journals,
articles, books, and other sources. The collection of data has
been done with the help of a secondary search strategy that
has been done in the form of examining and analysing the
studies that are conducted previously aimed towards Unity
game development mainly journals and proceedings of
conferences. To make this process more effective researchers
have set some restrictions. For example, the data is only
gathered from 2008-2020 via using several keywords like
Unity, Challenges, Benefits, Information Technology, and
Game Development from reliable databases like Google
Scholar, Academia, IEEE Xplore, Scopus, ProQuest, and
Research Gate. An inductive research approach along with
the interpretivism research philosophy has been adopted for
the demonstration of the insights and vital facets passably.
Therefore, the discussion and analysis have been conducted
through a content analysis technique in which relevant
themes in accord with the research objectives are formulated
to achieve the research paper aim and objectives [9,10, 11].
Therefore, the above-mentioned aspects of the methodology
are further supported by SLR (System or Systematic
Literature Review). SLR method aims towards identifying,
evaluating, and summarizing the state-of-the-art on a specific
topic. SLR permits for the restrictive compilation of
databases and enable analysis with less bias than traditional
reviews [31]. Hence, there are five stages of SLR such as the
construction of a question for the review; the documentation
of relevant works; examination of the collected sources;
synthesis of data and summarizing; and lastly, interpretation
of the findings. Hence, see Fig 3 for a clear demonstration of
SLR steps.

IV. DISCUSSION
In this section, based on the research objectives discussion
and analysis have been conducted. Relevant themes have
been formulated that ultimately support in discussing the
research objectives properly and also aids in achieving the
research paper aim.
A. To Examine The Benefits Of Unity Game Development
Engine
With reference to [8], it is found that Unity 3D comes
with several benefits that are not highlighted passable and, on
such facet, the researchers of this paper deem that this aspect
must be disclosed. Unity aids in processing, asset tracking,
scripting, and physics are some of Unity's game development
features that diminish game development costs and time and
offer elasticity when implementing projects on more than one
platform. Professionals have stacked the Unity engine at the
top of the ladder of multiplatform game development.
According to [12] it is found that this powerful cross-platform
game development engine permitted the development of
game applications for 27 diverse platforms and devices in a
user-friendly development environment. It bids affluence of
resources like ready-to-use elements, intuitive tools, tutorials,
clear documentation, and the online community for creating
amazing free 3D content in games. According to the survey
conducted in [13], Unity 3D Engine has a global market share
of Game Engine which is around 45%, while 47% of game
developers prefer Unity as a smart game development tool.
The developed and implemented application process via
Unity can easily be shared amid PC, mobile, and web
platforms. In addition, it is found from [3] the nature of Unity
has been grounded on the agile methodology that allows
constant release and rapid prototyping, which speeds up game
development. Likewise, Unity IDE provides the text editor
for writing the code. However, sometimes developers use a
separate code editor to avoid confusion. Moreover, the IDE
supports C# and JavaScript for scripting and offers important
functions that are suitable for game development. According
to [14] it if found that the Unity engine supports high-quality
video and audio effects that facilitate game development
smartly and effectively. Videos can be adjusted on all devices
and screens without compromise or distortion on picture
quality. Moreover, new developers need easy-to-understand
documentation that has been provided by Unity in detail. The
thorough documentation contains an explanation of almost
every single unit. The tweaking and debugging are easier
with game development accomplished via Unity remarkably
as all the game units and variables are depicted through
gameplay that permits the developers to debug the procedure
at runtime. The benefits of game development that are easily
available through Unity are depicted in Table 1 and 2 in
which some scenarios have been listed and how through
Unity such aspects can be attained that comparatively not
easy or passably achievable by other platforms.

B. To inspect the challenges that may emerge in Unity.
With reference to [15], it is found that Unity 3D offers
many exclusive features that permit developers to develop
diverse mobile games time-effectively. However, the
documentation for some of its functions is out of date and not
available for some functions. Up to Unity 5.0, the game
development engine is designed for 32-bit operation. This
means that the editor may crash wordlessly if a developer is

University of Sindh Journal of Information and Communication Technology (USJICT) Vol.4(2), pg.: 73-81
78
run out of memory. The engine is also not appropriate for the
development of AAA games. No new update for OpenGL
support to 4.X has been announced recently. Therefore,
functions like Computer Shader or Geometry Shader for OSX
or Linux are not available. Even the Unity licensed version
does not offer all mobile functions. In this case, you will need
a supplementary investment of $1500 to $3000 to operate
your Mobile Pro license. This seems a bit steep. The engine
is graphical upside down. It doesn't offer several other tools
for creating prudent graphics than other game development
engines [16]. In the Unity 5 game development engine, built-
in support for the PhysX physics engine has some challenges
regarding the performance, and it lacks in some key features
that need to be added to build the world-class gaming app.
Similarly, developers must have licensed to get the best
deployment, graphics, and performance advances. Likewise,
buying these licenses is expensive. The use of buffer support,
rendering, template support, and many other functions
increases the development costs due to expensive licenses
[15-16].
Additionally, it has been found from the [17-18] study that
the code is more stable in Unity than other engines and has a
fantastic architecture that advances the performance of the
game application. Yet, due to source code unavailability, it is
difficult to fix, find, and address performance issues. The
Unity engine influence more memory in accordance with the
game development that ultimately causes debugging issues
and OOM errors in the applications that have been developed
under the umbrella of Unity. Simultaneously, in the field of
game application development, organizations rank the Unity
3D engine for mobile game development on a priority basis
or it can also be stated as on the top of the list despite its
several challenges. Unity updated versions have incessantly
advanced the game development engine and fixed the exiting
challenges on a passable scale, which can also be considered
as one of the reasons behind their upsurge and immense use
in the domain of game development. Hence, each coin has
two sides; henceforth, even though there are challenges there
are also benefitting that is supporting the developers to attain
high-quality outcomes.
C. To Outline the Best Approaches of Unity for enhancing
the skills of Unity developers
The role of Unity Developer is comparatively new and
tougher to describe than some of its precursors. Some
developers focus the Unity only on the art side whereas some
prefer it for the coding that may help in the process of game
development. Nevertheless, [19] has quoted that somewhere
amid them there is more to do like building tools to aid out
their more exceptionally focused allies. As of this diversity,
it’s vital to look at the Unity role from an upper level to
classify the four wide-ranging approaches and skills depicted
in Fig 8 that benefit virtually in the context of accomplishing
the high-quality outcomes.
Figure 8. Approaches and Skills [19]
• Scoping and Pre-production; it has been considered as
the most vital aspect of Unity. It is also found from
[19] study scoping and pre-production are the two
most vigorous skills that must be catered and
considered by the Unity developer in order to be
successful. A sign of a good Unity developer is being
able to reliably ship goods, and one of the chief project
killers is feature creep. Moreover, Feature creep has
been well-defined by [20] that it occurs when a
developer or any other team member has another great
idea that needs to be almost completely integrated into
the game, which often leads to the next or equally great
idea to solve the problem. The most operative way to
evade feature creep is to create a project production
roadmap and plan) pre-production) before starting the
proper development in such facet a developer must
have to design and define exactly which functions they
want it in the endgame and what the end product will
look like in quantifiable terms, for instance, some
game characters, special characters, and others.
However, this does not mean that things do not change
during production, things might get changed in the
development process; nevertheless, it depends on the
methodology that is adapted for game development.
Therefore, in this regard, for instance, to mitigate the
sudden change in the game development professionals
and experts have set some tips and tricks that are allied
to testified and validated process that are present as per
the methods, guidelines, and approaches and amid
some beneficial facets scoping has been considered as
the vital aspects in every development arena whether
it is connected to technical and non-technical. Scoping
helps in pre-production facet that may occur in the
form of gathering and understanding the needs of the
end-users and by proper documentation such gathered
aspects are jotted it down that help in crystalizing and
transparency factors which eventually support in the
mitigation of feature creep and other challenges that
may impact on the overall game development process.
In addition, it is found from the [21] study that the
importance of scoping and pre-production is often
rejected by inexperienced teams or those from other
industries, but for the game development scoping and
pre-production is considered critical for the success of
the projects or products. Pre-production does not have
to be a formal or extended process. Just give enough
time to clearly define project goals and by locking it
adequately quality outcomes can be accomplished.
Scoping and Pre-production
Asset Store and Smart Use
Ubiqutous Programming
Emphasis of the Future: State of Art

University of Sindh Journal of Information and Communication Technology (USJICT) Vol.4(2), pg.: 73-81
79
Therefore, the researchers deem that a game developer
who is developing the game under the umbrella of
Unity must focus on this approach. It is also advised
that give pre-production time as long it requires that
ultimately help in accomplishing the quality outcomes
in the end-product. It might seem like a slow process;
however, if you are working on a project or product for
six months or even two years and have inevitably lost
track of what you are working on, it is very helpful to
have a document that helps you adequately throughout
the process of development as it helps in the mitigation
of assumption based development.
• Asset Store and Smart Use; Using the Asset Store is
often a bad name due to the increasing spread of flip
asset games that are flooding online sales platforms
like Steam. Developers can buy or purchase assets in
the Unity Asset Store and use the launched demo
scenes as the base for their own game. Even non-
developers have noticed that the store and some of its
most popular assets are used to flip. Also, the end-user
is generally unaware of how often legitimate dev.
successfully uses the asset store. A good example of
this is Blizzard's online card game Hearthstone, which
uses PlayMaker, a pictorial scripting tool accessible
from the Asset Store. Other popular games with
Playmaker are Inside and The Forest, Hollow Knight.
In these cases, it can be stated this approach of asset
store and its smart use has been considered as an active
method that has also been suggested to the Unity
developer to adopt for better retrieving the services
[19]. Therefore, it also ensures the success of high-
quality outcomes. In addition, the Asset Store is a very
powerful tool for Unity game developers throughout
the production stages if it is used intelligently. A great
way to imagine the Asset Store is with an up-to-date
resource library that an art studio like Disney needs to
support its team. From sound effects to moving
reference films, these tools are used as an early point
for an artist's creative endeavour. The key to making
good use of the Unity asset store is to look at it as a
way to rebuild the wheel. As long as game developers
make sure that what they have downloaded from the
Unity asset store aimed at setting up the best class in
the project despite adapting the things generally [22].
• Ubiquitous Programming; Although Unity may not be
programmable, there is ultimately no way to create
more multifaceted projects. However, you need to
know how to code C# and JavaScript as Unity is
supporting such two-programming language depicted
earlier. There are some workplaces but the good news
is that everyone can program easily which makes
Unity as ubiquitous programming platform that means
programing for everyone. Fans, artists, old, young,
everyone can learn to write C# and JavaScript and can
work on Unity and it is a famous quote that practice
makes you perfect and if someone had the potential,
he/she can easily work and gain expertise in Unity
game development easily [19]. However, this
approach has been suggested for both technical and
non-technical individuals that help in the success
factor. On the other side, it is found from the [23] study
that there is a widespread misunderstanding that it
takes a certain kind of mind to understand the
scriptures. However, solving problems with methods
and variables is itself a creative undertaking. Learning
a scripting language and writing your logic is more
than learning a set of rules and thinking in a certain
way. All it takes is patience and a desire to learn. It is
recommended that people interest in the game
development must work in accordance with the Unity
as it comes with ubiquitous programming that may
also help in their career growth as technology currently
and in the forthcoming time may play an active role all
over the globe and it is evident that global job market
will have a big ratio of tech-based jobs. Therefore, for
technical and non-technical people it is advised that
they start learning if they want to advances in the game
development arena for this, they may follow some
script tutorials then challenge yourself to create
something unique. Therefore, the more scripts an
individual write, the more they understand [24].
• The emphasis of the future: State of Art; being a Unity
developer is exciting with almost all Unity engines that
are released. Unity crosses the boundaries of what
modern game engines can do. Some of these new
features are still in the progression stage; however,
they are already in high demand as gaming companies
use new technologies to reap the benefits [19]. The
new main features that Unity developers should
address as quickly as possible are depicted in Fig 9.
Figure 9. Future and Unity
Scriptable Render Pipelines, it is inspected from [25]
that with the release of Unity 2018.1, end-users were
able to write custom rendering pipes through C#. This
means that developers can now regulate and cope with
how things are carried out to the screen smartly. This
can be helpful if the project has a dedicated look or
desires to be optimized highly. They also released two
templates of rendering pipeline: the HD rendering
pipeline for high-end consoles and PCs where graphics
quality pushed to its limits, and the lightweight
rendering pipeline for low-end devices like a cell
phone and platforms with special requirements like
virtual reality and a highly polished appearance that
surpasses the old rendering flow. Both templates give

access to new features like Shader Graph, a node-
based visual system for developing custom shaders.
This permits artists to get involved in creating
specialized shaders that reserved for programmers
exclusively.
ECS, it is a fundamental change in the way Unity
projects are developed, particularly in the way things
are written and scripted. Every developer who has
registered with Unity is familiar with object-oriented
programming [26]. However, ECS uses data-oriented
programming. Data-oriented programming is unique
because it offers integrated deep code optimization. If
it can be run, it is fully optimized. This approach of
Unity that has been based on the current tech-based
trends permits Unity projects written with the ECS to
push the boundaries, as newly revealed in Unite LA
Prime 2018 [19]. Unity's development plans with a
roadmap for public access are fairly open and often
reveal new features long before they are fully
published in the editor. It is good practice for Unity
developers to check the YouTube channel, official
blog, and roadmap itself regularly. While gaming has
been the main focus of Unity, more industries are
paying attention to what the Unity engine can do.
Therefore, it can be stated that connecting with the
Unity under the best practices and approaches is
considered as the great opportunity for developers
looking to expand their careers in the future, as Unity
developers have more job opportunities than ever
before that is evidentially and scientifically discussed
in this paper under the qualitative research.
V. CONCLUSION AND FUTURE RECOMMENDATIONS
To conclude, the paper aims was to develop relevant
understanding and knowledge about Unity for the better
comprehension of the people allied with the IT sector. To
achieve the aim, three objectives are designed such as, to
examine the benefits of Unity, to inspect the challenges that
may emerge in the Unity, and to outline the best approaches
of Unity for enhancing the skills of Unity developers. Based
on the three objectives, three questions are also formulated
such as; What are the benefits of Unity? To what extent the
challenges of Unity affect the people working in the game
development domain? What are the best approaches to Unity
skills for enhancing the skills of Unity developers?
The method that has been used throughout the paper is
qualitative research that is further backed up by secondary
data. Moreover, the method and search strategy are connected
with inductive research approach, and interpretivism research
philosophy for the achievement of insights and discussing it
smartly that helps in developing the relevant understanding
and knowledge of the readers. The content analysis technique
has been used to analyze the data that has been done via
thematic analysis. Therefore, it is found that Unity has been
playing an active role in the arena of game development, and
with the passage of time and effectiveness and efficiency as
well as the usage and devotion of industries to Unity is
amplifying. Thus, it comes with several positive impacts in
the arena of game development like firming careers, job
opportunities, and upsurging the value of game developers
intensively.
To recommend, the important thing a Unity developer can
do is to work on improving their skills continuously. The
technology industry is never static, and the work landscape in
five years will be very different from what it is today. A top
Unity developer is forever a student who learns everything
about Unity's new features as well as its time-to-time releases
and works eagerly to improve what they already know about
the engine so they can be prepared as per the current needs,
wants and demands that also support in the career growth.
Even though Unity has certain limitations, its advantages
outweigh its disadvantages. As such, it is undoubtedly an
effective podium for creating games. To choose a powerful
tool that gives great features is obligatory to develop an
adequate game that is available via Unity. Unity 3D is also
easy to learn and use as discussed in this paper. It offers a
very cheap pricing solution to meet the developer’s needs. A
free version of Unity offers most of the functions. Though, if
developers need advanced features that can always use the
paid version.
