All you guys who bought it are gonna hate me for this, I have very bad news. If you don't own it, well here's one more reason to pass.
If you complete a season in franchise mode, and get passed the off-season stuff, you'll find that your next season is 15 games or less. Absolute bullcrap! Supposedly not all game discs are affected (I got this info from the IGN boards), but I just simulated an entire season and playoffs and sure enough, bullflop. I bought a guarantee with my disc but I'm not sure if there's any point to returning it, since the store is likely full of the bum discs.
I suggest you sim a season in franchise like I did just to see if you were affected. Please don't hurt the bearer of bad news - my nerves are shot as it is. At least you can play a season and then change teams next season, but dang I was hoping franchise mode was good. Apparently not.
