If it were Halo 3, I would fall asleep after about 30 mins.
On the other hand, if I were given a completed copy of Super Smash Bros. Brawl right now, 2 months ahead of everyone else...
GOD I CANT WAIT FOR BRAWL TO COME OUT!!!!!! GODDAM ALL THE OTHER GAMES
ok sorry got a little overexcited there...
But if I were given Brawl to play, I would probably last about 60 hours cuz I would be so #$*%ing addicted
