I'd say you should add Nexuiz to that list (the GPL version, not the
proprietary version). It's pretty much Xonotic, however, it runs on computers
that can't run Xonotic for whatever reason, like mine. Xonotic crashes my GPU
on even medium settings, forcing me to have to reset, where Nexuiz can run on
max settings. It also has free content like Xonotic.
I'd also add these games to that list:
- Minetest: an infiniminer-like game where you build things and browse around
an infinite, randomly generated world. Still needs work, but quite fun to
play anyway.
- 0 A.D: A Free RTS game on ancient warfare.
- Neverball: A 3D arcade ball puzzle game.
I may have another game to add, but I'm trying to confirm that it's actually
libre before I do so.
