I'll admit I had not read the whole thread before posting, mostly just the first few points, but scanning through it after the fact I see an awful lot of people talking about the gameplay and not the sim engine.
That's cool if you're playing 7 minute quarters to make the # of plays more realistic. I used 6 minutes myself in NCAA 08, although now that I'm playing OD in 09 we're using 5, wasn't my choice. Sadly, with a realistic number of plays I'd imagine your games are probably averaging a total of at least 65 points per game between the two teams (played games, not simmed) which is not realistic at all. I think if people played a realistic number of plays
and had a realistic number of big plays and points in the game on a regular basis, they'd get quite bored.
