Best multiplayer games?

What games for the PS2 have really fun multiplayer? Not online multiplayer, but offline multiplayer.

Sports= 8 players( A BLAST)

007 agent under fire= 4 players

ATV 2/3= 4 players.

I might buy some of these games, tell me more!

You might want to narrow down what you are looking for as in First Person Shooter, RPG, Action... I would say some of the best are:

Champions of Norrath

Champions of Norrath: Return to Arms

Baldur's Gate

Baldur's Gate II
