Little update about FLOSS games on Steam:
- Destination Sol:
http://store.steampowered.com/app/342980- Tales of Maj Eyal:
http://store.steampowered.com/app/259680 (dunno why I hadn't listed it before)
- CaesarIA:
http://store.steampowered.com/app/327640- Evolution RTS:
http://store.steampowered.com/app/291150- HyperRogue:
http://store.steampowered.com/app/342610(the current version on Steam is not strictly speaking "open source", since it's newer than the currently available GPL version (
http://www.roguetemple.com/z/hyper/download.php ). But the developer claims that the content of the Steam version will eventually be added to the GPL version too, but with a delay (which is a perfectly fine commercial model for free software IMO, as long as the dev keeps his promise).
There might be a couple more that I missed, and I know I saw other open source games on Greenlight (at least Hydra Slayer by the same dev as HyperRogue).
