Open-source video game

An open-source video game is a video game where the source code (the instructions and programming language used to create the game) is open for anyone to look at, use and modify. This means that people are free to look at the code behind the game, copy it and make their own versions. They can also change the game to make it better, add new features or fix any problems. With an open-source video game, anyone can improve it, no matter their skills or experience.
