As much as I want to agree with you my friend, the points you make are logical and make sense.
But when it comes to some 2k fans no matter how much Madden improves or even if Madden ends up great. It will be a hated game by them and they would rather re-create the NFL in a generic game from 2k just because 2k made it.
Basically a customizable game is for those loyal fans who refuse to purchase EA sports games no matter what. That is reason these threads keep popping up and it's also the reason people keep hope of another 2k football game with customizations. They want a NFL by 2ksports and not EA, so they'd rather recreate the NFL in a 2k game. It's the who basis of the request. No one wants to feel forced to by Madden because it's the only choice. And they also don't care if it's bad or good they don't want it because EA made it.
So every year we will get these hope threads until that license has expired. Problem is 2ksports has fallen off thanks to Take-Two. If any other publisher knew the amount of request for these titles, and knew the need for it to satisfy the consumer they would have already put it into development. I'm pretty sure Visual Concepts are shaking their heads constantly at these threads not because they are laughing at us or the community but because TT won't lift a finger or a budget to even try. They've already waved the white flag to NFL and have put Visual Concepts in a corner.
