Despite the obvious visual upgrades, Madden '06 for the 360 is even worse than the re-tread game that is on the Xbox.
In this Xbox 360 version, you get very nice looking graphics. And that's about it. Most of the gameplay features were stripped out due to the timeframe this game had to be released on. And any annoyances you had with the earlier Xbox/PS2 versions of the game were still here in all their glory.
The main problem with this game is that it didn't add anything good to the gameplay and stripped the game of most of it's features. Obviously, that is a mistake and I can't believe EA let this out the door and charged $60 for it back when it was released. Then you have the core-problem of the game itself. The 'new' features are all pretty lame and the most hyped of them all (the cone vision passing), is one of the worst features I have ever seen in a videogame. EA basically admits to this, since the cone-vision passing is auto turned off in this version (unlike the 'current-gen' games).
Essentially what you have here is EA trying to cash in on a new console. Sure the graphic upgrades are nice, but this is a rushed game that shouldn't have made it out the door in this condition. The only reason to buy this game is if you can get it at a heavily discounted price ($10) and you are going for the easy achievements. And if you must own a Madden '06 game, I would recommend the Xbox version of this over this rushed turd. I would give this a rent, get the easy gamer points, and never look back.
