Open Source games for Linux

Linux Journal is running an article on free open source games available for Linux.

I have installed the following games that are available on the Ubuntu repositories - Torcs, Trigger, Open Arena (based on Quake 3). Unfortunately my graphics card does not render these quite well. Time for a new machine, I guess!

$ sudo apt-get install trigger torcs openarena

LinuX-gamers.Net has an excellent repository of information related to games for Linux.
