Whats the best party game?

All my brothers and most of my cousins are going to be coming down next weekend, anybody know of a good party game that would be fun to play? It can be a disk or on Xbox Arcade.

ya that definately is outta the price range for now

If you like trivia Scene It! and 1 vs 100 is good. Fighting games seem to be popular here for me. It's funny seeing a girl, or anyone who never plays games, button mash her way to victory on someone who thought he was the best.

Yeah fighting games are good, also try Marvel UA, four people can play at once.

You could try castle crashers. It has 4 player coop.

Rock band and Street fighter 4 are great.
