I don't give rat's ass about Madden and I'm interested in trying out this game. Of course we can't predict just how the "real" Madden fans might feel about it. For all we know, they might actually avoid the game because it's different. Plus, Madden's always been more popular on PS/XB, so the fan base might actually hate it just because it's different.
I honestly hope they don't think that way. I mean, the Wii actually forced EA to create something original, and that speaks volumes! If the game's good, it really does deserve our support and money.
