Game development is the process of creating video games, which involves several stages including concept design, programming, art creation, and testing. Developers work in teams to bring ideas to life, using various tools and software to build the game's mechanics, graphics, and sound. This collaborative effort can result in different types of games, from simple mobile apps to complex console titles. The game development process often starts with a game design document, which outlines the game's concept, gameplay mechanics, and target audience. After the initial planning, developers use programming languages like C++ or Python to code the game, while artists create visual assets. Finally, extensive testing ensures the game is fun and free of bugs before its release.
