Game design is the process of creating the content and rules of a game. It involves the conception and development of the gameplay mechanics, storyline, characters, levels, environments, and user interface. Game design integrates artistic vision with technical knowledge to create engaging and interactive experiences. Game designers often work closely with programmers, artists, writers, and other team members to bring their vision to life. They may also use prototyping and playtesting to refine and iterate on their designs, ensuring the final product is fun, engaging, and polished.
