Best Mutliplayer Game Played???

[Aoi Denkou]

Halo 3
Super Smash Bros. Brawl
2 great games with awsome multiplayer possibility's.

 

[Shadow Tyrant]

TEAM FORTRESS 2.

Also Brawl is pretty good.

 

[ThaBenMan]

Rock Band, Mario Party.

Not a fan of multiplayer FPS.

Define what the topic means by "best". Does it mean the most popular?(As in most played), your favirote?
As for the former I say Warcraft 3, for the later GTA San Andreas (It has multiplayer mods so it counts)
