been addicted to it for over a half year and still play it every day.
Try http://tremulous.net/, it's an online FPS/Strategy-Mix and uses the Quake3-Engine.
Basically it's about a battle between humans and aliens, the interesting part is that you can also play on the alien side. While the humans use guns, laser-rifles, granades and other technical stuff, the aliens bite, beat, or trample down the enemy.
Along the lines of Quake 3 engine based stuff, there's OpenArena at http://openarena.ws/
There's also a game called Sauerbraten (http://sauerbraten.org/), which has the rather nice feature of multiplayer map editing, where anyone in the game can edit a map while in play
Toribash is a great game/sim much like truck dismount, except you have to contract/expand various joints of a person to injure( or decapitate) the other player within the minimum number of frames
