I play Xonotic, a free software FPS that uses the Darkplaces engine. If you're up for twitch shooting, play instagib. If you want action, hop onto a Clan arena match (team Deathmatch but 1 life per round, and you start the map with everything). OTOH if you're too tired to frag, hop on a Xonotic Defrag Server, where your only goal is to practice movements to finish a track on time. Xonotic has some very cool quake like movements, and there are almost always people on the Relaxed Running server (but they also have >1 hr puzzle/trick jump tracks). It's so much fun, even just for the 20 minutes I can usually get before going to bed ;)
