I'm not going to claim we got the shaft unless when the game releases we have a SimCity style disaster and nobody can play the game on 360. As long as the game is ready on release, I'll be upset I don't get to play as long, but it is a test and if it's ready you cannot really complain.
Just accept that Xbox is 2 days and move on already. Not going to change anything. Play what you can for as long as you can. yes, Ps3 may get 6 days but I will be lucky if I get 2 hours a day to play.
