A game designer is a person who designs gameplay, conceiving and designing the rules and structure of a game. Many designers start their career in testing departments, other roles in game development or in classroom conditions, where mistakes by others can be seen first-hand.
For video game design, see Video game design. Game design is the art of applying design and aesthetics to create a game to facilitate interaction between players for entertainment or for medical, educational, or experimental purposes. Game design can be applied both to games and, increasingly, to other interactions, particularly virtual ones (see gamification).
