Why do xbox exclusives sell more than ps3 exclusives ?

[Black_Scurge]

I just compared the sales for ps3 of all games published by Sony and all 360 games published by MS (after the ps3 release so it's the same time frame) I used VGchartz search

MS

Sony

I ignored kinect adventures since no1 bought it they got it free with kinect, and took out all the games that are there cuz of a glitch and Sony took the lead when I got to games that sold .70ish mil on ps3 I plan to make a thread with a chart when I have enough posts, so it's not the middle selling games that makes up the difference for Sony it's the mass of low selling games
