@boilingsteam (The 4 options listed ensure that the games are not yours, while with free software, the game is always yours, whether or not you pay money for a copy).
@Suiseiseki It's not like you have a lot of choice though. There are very few FOSS games out there, and they certainly can't compare with the commercial offering. It's not what I like it to be, but it's the reality.
