If you’re looking for pirated stuff, forget it, there are no sites that do that.

If you want top-notch free games, meaning real GPL stuff, as opposed to freeware, shareware and abandonware, try www.happypenguin.org

It is the linux game tome, a collection of the best free (gpl) games on all platforms. Most games are available in both linux and windows. There are well over a thousand titles, all free to download. Nothing commercial about this site. There are a few commercial games listed but over 95 percent of the games are entirely free.

This games are expecially good:

Open Arena (quake3/4 client)
Tremulous
Wolfenstein ET
True Combat Elite
Legends
Savage2
Defcon
Sauerbraten
NERO
elc
targetware (air combat)
Frets on Fire (like Guitar Hero)
