Realistically, what is the biggest franchise that Microsoft can buy out that would give them first place in console sales?

Madden COD or Mario.

I'd put Fifa in place of Madden.

Fifa in Europe would sway a huge amount of gamers there. COD in NA and Europe, and Mario could bring over a lot of Nitendo fans and casuals and generally worldwide appeal.

Perhaps if they had all three. It would certainly be amazing to see that happen, the biggest megaton in the history of the industry and it would provide some very entertaining reading on vgchartz.
