Some of Madden NFL 12's biggest improvements are in presentation. Grass now looks like grass; player animations are more fluid and dynamic than past games; and the new stadium lighting models look amazing. Every game is introduced with NFL style camera angles and pageantry, which is a nice touch and really cool, at least the first few times you see it. Then you start to notice the smaller issues. With the exception of the players, everyone else looks stiff and lifeless. I also had a major problem with player's eyes. I know it is a relatively small issue, but they look creepy and are a bit of a distraction during replays.
Speaking of replays, I'm not sure how they work. Most of the time they make complete sense, yet other times minor plays get a replay while big plays don't. Replays also showcase some of the audio problems. Commentary, once again provided by Gus Johnson and Cris Collinsworth, is terrible. If they're not a few steps behind what is happening on the field, they are overlapping each other's thoughts with mechanical banter. Collinsworth uses the same flat delivery, while Johnson's words ineptly move from excited to dull.
A few technical details pop in as well. The volume and quality of commentary will abruptly switch. One minute it is loud and clear, the next it isn't. At one point, it even sounded like Collinsworth was calling his thoughts in through the telephone.
