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.Whats the best party game?
Rock Band/Guitar Hero WT is always fun to play. But its pricey.Whats the best party game?
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.
3 on 3 NHL is ok. Castle Crashers is better. The only good disc party games are GH and RB.
Castle Crashers gets my vote. The game is so much fun to play with your friends.
If by party games you mean a collection of mini games then Fusion Frenzy is worth a look at. Not all that great a game to play solo, but can be fun for playing with friends, and is bargain bin price.



Games that have their own controllers like You're in the Movies (Live Vision cam), and Scene It! (4 large button controllers) are also good fun for groups of people.



Guitar Hero and Rock Band are good fun for a group of people, but they are a bit pricey if you look at getting a full band, or even just a game and two guitars.
Scene It!

Castle Crashers

Halo 3

Guitar Hero II (if the newer GHs are out of your price range, I'm sure you can find GHII for cheap. It's also one of the best in the franchise's history)

Call of Duty: World at War (Nazi Zombies for up to four people? I'm in!)
