the question i have
the 360 version do you also have to do a 20min install or could you...i don't know...PLAY the game?
if you can just slap in the disk and be playing within a minute or two- heck lets call it 5 minutes- on the 360..and there is a second savings on load times on the ps3 of ~1 second per loading sequence... you would need to do.....15x60 or 900 loading sequences to "catch up"
2 people loading game... person 1 ps3 person 2 360...5 minutes later person 2 starts playing...
15minutes post that person 1 starts...
if both players are equally skilled and go thru each level in the exact same timeframe, every ~60 loads of a level/cutscene the ps3 person would gain a minute back. ~900 loads later they'd be equal in the game...
