Part of it would have been the exclusivity, but part of it may just have been the popularity of the Xbox.
Still, Microsoft must have one big grin. Bethesda don't have anything to complain about either, with those sales figures!
I don't agree completely. Sure this kind of sales show how popular Skyrim is but this doesn't mean that everthings perfect. How many bugs and glitches does the game got? Mostly on PS3, I will tell you it's to much! You have to deliver both quality and quantity. In this case quality is not perfect. Like Fallout New Vegas (I know not the same studio!), but still to much problems. Don't get me wrong I love Fallout NV and Skyrim, but they have to do better next time.
