I'm sorry but the Xbox One got a boost from a free game offer. Comparing the effect of Madden on sales is faticious because it was given away for free. I am absolutely certain that you will get a bigger % boost from a game that cost $0 on one system than from a system that charges $60 for the game. Watch Dogs bundle didn't include a free game. And since the package in its totality was cheaper on the Xbox One, how do the total sales of both Madden (PS4) and the PS4 itself factor into your theory. Can you give an explanation? Or was I tricked into responding to a joke thread?

Let's forget about the rest of the world. Those preorders are US only. :p

Madden Bundle + People holding off for the Destiny PS4 Bundle are the reasons for the higher boost in terms of percent for the Xbox One. Still, Madden on PS4 outsold the Xbox One version...
