I'll take it, and I'll edit in what game I think will beat it when I get home.
Edit: My nonsense numbers, competely out of my ass and off the top of my head-
NSMBWii's 2010 numbers - 6.3 million
GT5's 2010 numbers - 6.8 million
I have no supporting evidence, it's all nonsense to me. But I'll eat crow if'n it dunna happen. Und you can quote me.
