If you've played Paper Mario and Paper Mario: The Thousand Year Door, you'll have to get used to the new battle methods. Instead of going into a battle sequence where you take turns, they're more 2-D side-scrolling battles. I bought the game last weekend, and have been playing it a couple hours each night and I think I'm half way through right now. It's a pretty good game, and makes use of the Wii technology nicely. I really enjoy the ability to swap Mario with 3 other characters as well. Not telling you who :P

Great game overall in my opinion.
