Nice multiplayer games??

Good LAN games I know:

TrackMania Nations Forever

A free arcade racing game. You can create tracks and race against eachother online or over LAN easily. It's really addicting making tracks. I spent 4 hours the other day making a tribute track to Delfino Square from Mario Kart. There's also a shareware version called Trackmania United Forever, which is the same but it adds more car customization and more maps to build tracks on.

Worms: Armageddon

Yeah, this is a pretty old game and you might have compatibility issues. But this is the best of the Worms series. It's a side-view arcade turn-based shooter thing. The dozens of weapons and destructible terrain, as well as the hilarious taunts from each Worm make this game a lot of fun.

MUGEN

This can't be played over LAN, but if you have some USB game controllers then you'll have a blast with this one if you enjoy arcade fighting games. MUGEN is a fighting engine that lets you download user created characters, stages, menu screens, etc. You can turn it into anything! However, it's not very user friendly and there's a lot of INI files you have to manually edit to add content to the game. I think it's worth it though. Imagine all the characters from Killer Instinct, Mortal Kombat, Street Fighter, Melty Blood, Capcom, Nintendo, etc. fighting against eachother in one game!

Battlefield 2

This is another old game, but it has the best multiplayer of any game yet. It's a modern warfare game with tons of vehicles like HUMV's, helicopters, tanks, fighter jets, etc. The graphics are outdated, but it's still fun. You might want to wait for Battlefield Bad Company 2 to come out in Marchthough, since it seems like a MAJORLY updated version of Battlefield 2. (and is also very fun! I'm in the closed PS3 beta, and Gamespot is giving away beta keys I believe if you have a PS3)

Other Co-op games I don't really know much about but look interesting:
Blazing Angels
Kane & Lynch: Dead Men
Terminator Salvation
