Open Source Game Clones

List of games

A Remake is a game where the executable and sometimes the assets as well are remade open source. Some of these games aren't exact remakes but evolution of original ones, which were eventually open sourced.
A Clone is a game which is very similar to or heavily inspired by a game or series.
A Similar game is one which has similar gameplay but is not a clone.
A Tool is not a game, but something that assists in playing or modding the game, such as a high resolution patch, or resource extractor.
