2. Development is overseen by internal and external
producers.
Internal Producer: The producer working for the
developer manages the development team, schedules,
reports progress and so on and is known as the internal
producer.
External Producer: The producer working for the
publisher is called the external producer and oversees
the developers progress and budget. Producer's
responsibilities include PR, contract negotiation, liaising
between the staff and stakeholders, schedule and
budget maintenance, quality assurance, beta test
management, and localization. This role may also be
referred to as project manager, project lead, or director.

3. A video game publisher is a company that publishes video games in which they
have either made themselves or had someone else develop for them such as
another company. Just like books, films etc the publishers are responsible for
distributing, advertising and market research.
Usually the development is financed by the publisher, sometimes by paying another
developer or by themselves internally which is called a studio. Another thing that
are often performed by the publisher is paying for a license that the game may
utilize. For example paying for localization, layout, printing and sometimes writing
the user manual and creating the graphic design elements.

4. Developers can vary in size from small groups making casual
games to larger groups which hire many employees which produce
large titles. Usually the companies divide their game development
into subtasks, similar to films. The size of team differs from 20 to
100 or even more depending on the size of the game. These roles
are taken on full time work.

5. A game designer is someone who designs the game play
and conceives the structures and rules of the game. It is
common for development teams to have a lead designer
who leads the other designers in the process. They are
seen as the main visionary of the game and one of their
main roles is often being the writer. Usually they are
employed part time to create the games narrative,
dialogue, commentary, cut scene narratives, journals,
video game packaging content, hint system etc. Obviously
for much larger games such as Grand Theft Auto there will
be more than just one Lead Designer as It is a very big
game which one person could not create that much detail
and ideas on their own.

6. A video game artist is a visual artist who create the overall
video game art. They are usually overseen by an art director
or art lead making sure that the directors vision is followed.
The art director manages the art team, scheduling and
coordinating within the development team.
If the artist is 2D oriented then they may produce things like
concept art, sprites, textures, environmental backdrops, or
terrain images. Whereas the 3D artists may produce models,
meshes, animation, 3D environment and cinematic, although
sometimes the artist can have both roles.

7. A game programmer is a software engineer who develops video games or related software.
The game's codebase development is handled by programmers. There are usually one to a
few programmers who put the game's starting codebase in place and overview the
development.
Programming roles include:
Physics – the programming of the game engine, including physics, collision, object movement,
etc
Graphics – the production of graphics engine, models, textures to work along the physics
engine.
Sound – music, speech, effect sounds into the proper locations and times.
Game play – games rules and features
UI – User interface elements such as option menus, HUDs, help and feedback systems, etc.
Input processing –compatibility of different user input devices, such as keyboard, mouse,
gamepad, etc.
Network communications – the managing of data inputs and outputs for local and internet
gameplay.

8. A level designer is what it says. The role of the level designer is to create
different levels/challenges/missions for the video game using a certain set of
programs. These programs can be either commonly available for companies
to use or they can be specially designed and made for a specific game. For
example Grand Theft Auto uses a specially designed program. Level
designers work with the game when it is both incomplete and complete

9. Sound engineers are responsible for the sound effects and sound positioning.
Sound positioning means that the a sound is activated by a certain action, for
example when firing a gun on Grand Theft Auto the sound engineer will
implicate a specific gun noise to go off when that gun is used.

10. A quality assurance test is carried out by game testers. Game testers
analyzes video games and give feedback on parts of the game as a quality
control. This means that they ensure the game works within its initial design:
the game works and is also entertaining. This involves testing everything in
the game such as features, compatibility, localisation etc. Because testing is
an expensive process it is usually performed towards the end of the
completion of the project.
