A great football game.
There are a few flaws that keep this from being a great game. 1) Fumbles. There are way too many fumbles when it comes to All-Pro playing. Got a problem with that? Get used to it. I've never fumbled more than 4 times in one game, but I've heard stories of 8 and 9 fumbles per game.
2) Interceptions. Both sides of this make me a little pissed. The defense in this game is ridiculous. Sometimes they'll stop on a dime, turn around, and catch an interception. Hell, sometimes they'll reach through your player and grab that ball!!! Okay, the defense is a little over the top, but why can't they catch a ball thrown at their face? Sure, a diving, one handed interception is easy but you can't catch it at your face? BUT after playing your fair share of games, you'll get used to this and start making better passes.
If you don't mind the larger than average amount of turnovers, then this game is perfect for you...or if you like to play on pro. Some of the good stuff are: the Hall of Fame players in Franchise mode
Weapons aren't bad, but a little over-powerful
There is a create-a-team, but I haven't tried it yet.
Superstar is mostly the same. If it ain't broken...
XBL play is pretty fun...until that little bastard you're playing quits.
There are mysterious level rings. I honestly have no idea WTF these things do. CPU is a little smarter.
If you have NCAA 08, stick with that. I made the mistake of trading NCAA in for Madden 08. Don't get me wrong though, this is still a good game, just a few things here and there that can make you throw your controller once in awhile.
Buy or rent? Rent it first, but I wouldn't be surprised if you ended up buying it soon after.
