Computer games designers devise new computer games and define the way the game is played and the 'game experience'. They develop:
* the rules of the game
* the setting and environment
* story and characters
* props, weapons and vehicles
* different ways the game may be played.
It is part of their job to convince other members of the team to develop the game. They work with programmers and artists to turn their original vision into a working game.
During the development of the game the game designer is responsible for:
* directing and working on the fun aspect of each game
* making sure that the rest of the team understand the concept of the game
* making adjustments to the original specification to reflect technical constraints and new programming or artistic developments from the team
* training testers to play the game - they make sure that it works in the way it is meant to
* making sure the game experience meets the original vision.
