I do.
I want football to played well on a football game.
If that doesn't happen, all the realistic atmosphere and grass getting chewed up and halftime shows don't matter to me.
I liked 2K5 - not for the halftime show, but for the depth of the gameplay and the weekly planning system.
Maybe because I'm a text-sim player at heart (OOTP, Baseball Mogul, etc) I care less about graphics over balanced and realistic gameplay and game systems, but I would MUCH rather have Madden play the game of football very well over giving me the TV-Show like presentation.
MLB The Show was brought up. It's awesome in commentary - but if it played a poor game of baseball, I would be saying "that's nice - great commentary" and not play much because the sport itself is played too poorly.
Given the way the Madden gameplay is, I'm not asking for less by wanting it perfected as much as possible.
