Yeah, it's a fantastic game. Surprisingly hard in the latter levels given how easy the prior NSMB games were (well I haven't played NSMB2 yet). Makes me wonder if I'll be able to get through the Luigi expansion since it's supposedly much harder.
I'm really looking forward to playing 3D Worlds. I don't have it yet as some asshat stole packages off our doorstep, including a couple that had all our x-mas gifts from our parents.
Enjoy. I've been surprised by how much I like mine since impulse buying it a couple months back. Haven't gotten to play it as much as I'd like with the move and family in town for a couple weeks around x-mas etc.
I got an RROD on my first 360 just a bit outside of the 3 year warranty (bought in October 2007, RROD while playing Dragon Age Origins on New Years Eve 2010. Other than that I had no hardware issues. I never used the Wifi though I I keep my router on my TV stand so I can just use wired connections on my consoles and BR player for the streaming apps.
