Game design is the process of creating the content and rules of a game. It involves planning the gameplay, story, characters, and environment to ensure an engaging experience for players. Designers use various tools and techniques to develop the game's mechanics, balance, and overall flow. In addition to gameplay, game design also considers user experience and visual aesthetics. This includes designing user interfaces and ensuring that graphics and sound enhance the player's immersion. Successful game design often requires collaboration among different roles, such as game developers, artists, and sound designers.
