Yeah, just school & food.
Actually, you can just sit in one spot for hours without having to move (you wouldn't need food ).
Hmmm, that'll be awesome, you can get 16 players to go on rampages and kill cops.
That's like the ultimate party game.
I really don't know how any games can top this, and how the next GTA game will top GTA IV (besides location, characters & etc).
EDIT: Hey, if you ARE able to play pool, bowling, darts, etc in multiplayer, does that mean you players can kill the people that are playing the mini-game?\
Think about how pissed you'll be at the person.
