There are some good games for Linux, real problem is nobody maintains the packages for them. I downloaded a 600 meg Ubuntu 13 DEB package for Sauerbraten (Cube2)
and it was the old version. I then had to go to a Russian site to get an RPM for F19 and it was compiled wrong. Almost a gig and a half of wasted bandwidth! Nobody wants to play Assult Cube (Cube1 engine) but that's all Red Hat put in their repo. It's like nobody feels like helping the "community" (to use word loosly) of little tyrants who are running these distro... myself included.
I think I'll make an RPM just for myself though.
