What the? No GBA or DS Madden on that list? Preposterous!
Yes sportsfans, in America people support this like the Japanese support Dragon Quest. But unlike DQ, Madden is always the same exact game; but with marginal "improvements" that wreck the gameplay.
It's sorta like saying, how many times can a dog eat its own crap?
I do recall that in 2006 when you shut off the precision pass thingy, you had essentially Madden 2005; and when you changed the control scheme it became essentially Madden 2004! Waddayaknow! Either it was (at least) three games in one, or what may have been the first downgradable game ever!
