Sliders and user manipulated settings are something that still plagues madden. For the offline user (me), we cant efffectively use the sliders to fix gameplay issues because there a mess.
In my opinion the two things that seperate madden and nba 2k gameplaywise are animations and a multitude of effective sliders. If madden could nail these down there wouldnt be much of a difference between the two titles (again, gameplay wise).
