Topic on Talk:The big list of DRM-free games on Steam
I forgot to log...
There are many lists of Steam DRM free games: http://steam.wikia.com/wiki/List_of_DRM-free_games http://www.gog.com/forum/general/list_of_drmfree_games_on_steam/page1 http://www.drmdatabase.net/database/drm-free-games http://www.rpgcodex.net/forums/index.php?threads/list-of-steam-drm-free-games.80007/
They are not complete at all, and there are some wrong claims like all DOSBox games are DRM free (they are not). I need a week to two to add all games and test them.
