I'm not sure where I fit in anymore. I doubt I've played more than 30 games of Madden since Madden '05, but I would also enjoy sim play if it were possible.
IMO, sim play is impossible on Madden. Fundamental aspects of the game are missing. In my experience, there's not much you can do to make Madden sim unless your idea of sim is simply a realistic outcome(score/yardage).
Outside of some basics like rules and terminology, I'm not sure what anyone could learn from Madden. The strategy needed to excel in Madden is not the same as the strategy needed during an NFL football game.
Can you give an example of something you've learned from Madden outside of rules & terminology?
