More DRM-free games found/confirmed (all of them tested on Linux):
·
Sisyphus Reborn: completely DRM-free, no action needed
·
UFHO2: needs the 'steam_appid.txt' trick to work
·
Manual Samuel: also need the 'steam_appid.txt' trick. The fullscreen is a little messed up, but it can be perfectly played in windowed mode (and without the Steam client, of course )
