That's a very good point...in my Campus Legend on NCAA I'm a WR, and I've had so much fun running my routes, calling for the ball nearly every pass, and trying to get as many yards and TD's as I can. Doesn't always work, but in the game I'm the ultimate TO, I love me some me. Sure, it's "cheese" and "not realistic" but boy do I have fun playing it.
I suppose now I start to wonder if games are ever going to get so hard where they're not fun. I enjoy the mental aspect of football, but will defensive AI get so good that in order to have a chance of winning you have to watch imaginary game tape, learn the various defenses and all the weaknesses/tendencies, so you know where to pass and run? I really hope we don't reach the point where it moves from "fun" to "work"
