Little-known games good for LANs

I'm setting up a LAN, and was thinking that it would be nice to have some games that arn't too well known that would be great for such a event.
Something where everyone is new to.

Any suggestions?

AvP?
that lego building game

>>2 rocks.
But AvP2 is superior. It's great for LANs for two reasons:
1) It's not (just) about winning, it's about surviving as long as possible (which is quite hard for the humans).
2) You get to see the expression on your friend's face when you drop down out of a dark corner and bite their heads off.

It's quick, easy, fun, and free.

Fucking soldat.

Worms World Party is awesome, too, but can be randomly buggy on new systems, ime.

Get Worms2 too, lets you edit weapons more...unfairly. Makes for some hilarious matches. Shouldn't be too much anyway since it's kinna old.
ahh, max power banana bombs with max clusters, how I love thee.
