for dead rising for the 360 do you actually have to play 72 hours to beat the 72 hour mode?

Answer 1

Thats insane. But its not 72 real time hours its 5 realtime minutes for one hour in the game. So play for 5 minutes its one hour in the game.

Answer 2

You'd probably be able to save your progress as you go, but ya never know. On Gran Turismo 4 for the PS2 there's 24 hour races and you've got to run the entire race with no save options!!!!
