Open Source Game Clones

Open Source Game Clones

This site tries to gather open-source reimplementations of great old games in one place. If you think that some information is missing or have any suggestions - feel free to contact me by e-mail or submit a pull request via Github.Since all these projects are open-source you can help them and make this world a better place. Or at least you can play something to appreciate the effort people put in them.You may also be interested by Liberated Games, a resource, dedicated to cataloging all full commercial games that have been liberated and made free in playable form to the public.All games that were added in last month are highlighted like this.
