Quake 2 is a commercial 3D action game from id software, the makers of Doom. It is a shooter with a first-person perspective, in Doom's tradition. The game comes with three display methods. Anybody can run it on a virtual console (using SVGAlib) or under X. If you've got a 3D accelerator board based on the Voodoo chipset from 3dfx Quake 2 can use it to improve the display quality.
