Planet Unreal- Planet Unreal is a good place to go for Unreal Tournament info.  The fourms are also a good place to talk to other Unreal players, and listen to them bitch about their video cards are not working right.

Planet Quake- Go here, if you actually care about the garbage that is known as Quake 3.

Ritualistic- This is the place to go for SiN news.  As if anyone cares.  You can also check out their fourms, if you like taunting the LOSERS that dwell there.
