As a near-lifelong fan of the PC versions of Madden, I couldn't want to get ahold of this version when I get my 360 recently. Having now played the game I can say that I have no idea where the favorable reviews are coming from. It is an outright abomination.
The graphics and (visual) presentation are amazing. Unfortunately that's the one and only thing that this game gets right. Players seem to float around the field with no sense of weight or momentum. The difficulty settings are as poorly-tuned as ever, the play-by-play home team radio jerk is grating and the simulation engine is laughable. 3-4 backs will threaten to break the single season rushing record every year, I had Aaron Kampman record 38 sacks in a season, and at one point the Detroit Lions had 8 quarterbacks on their roster. And what's truly amazing is that EA has actually managed to remove features from the current-gen version: slide protection is missing, there's only one camera angle (see below) Madden's presence in the game is virtually nonexistant. Yeah, the canned clips of him and Michaels were getting really old, but it says something that the radio guy's voice is so annoying that I want him gone even though he actually does much better commentary than they did.
The cameras are particularly troublesome. Only one angle is available and it's so poorly implemented that short passes to the sidelines, or any passes to the flat, are a guessing game. I've read some people saying this makes it more realistic... just like in the NFL where any cornerback within 10 feet of the line of scrimmage is invisible. Speaking of which, want to control a cornerback? Good luck. You can't see him or the wideout he's covering until they're 10 yards upfield.
I've read that the simulation engine will be overhauled and more camera angles will be available in '09. Hopefully they fix the physics and in-game AI too. This version isn't worth the plastic the disc is pressed on.
