It's a fantastic feat. Though I can't think of why we'd look at MW2 as seperate games.

Anyhow, I really don't care. If it's to be treated as the fastest selling game to some arbitrary number, so be it.

Ya,

NSMB - Fastest exclusive to 15 million

MW2 Fastest game to 15 million

 

That basically sums it up.

NSMBWii 1 platform

 

MW 360,ps3 two platforms

Wii 72m

PS3 35m and 360 40m

so what about having two platforms for one game and one platform for another make it unfair when they have comparable user bases?  What is the actual argument, and not just "2 platforms is unfair" but tell me why.
