Madden 06 on the 360 feels slow and unresponsive, but can be fun for a rental.
So you want Madden...I say rent or borrow first. It's kinda love or hate and I'm leaning towards that hate one.
The game itself relies WAY too heavily on animation. Like once it triggered an animation of my linebacker getting shook right before a safety. Or my guy being triggered to dance out of bounds instead of running. Fanchise mode still isn't that great. The thing I love about 2K sports games are the generated rookie faces (you'll know if you played one). Even if that guy is Lance Briggs with some other skin tone, you get a feel for the rool instead of some faceless thing.
The graphics are pretty, but you are always too far to see them. I fou go to to coach's cam, you can't go back to the LOS view. Anyway, player models are great, faces too, and get mud on their helmets and uniforms. Also, the reflections on helmets rock. It's fun to do instant replay and stare. Except hit detection is horrible and they animate stiffly.
Sound is bleh. The new announcers (while 100% better than know it all Madden) are weird. Instead of sounding like a TV broadcast, they sound like a radio. It makes my ears hurt. And the "biased hometown radio announcers" always root for your team.
I dunno. Hardcore Maddeners will probably love it, but you may want to rent it or borrow it from that kid with a 360 down the street first.
Oh yeah, Madden 07. I'd probably wait for that.
