I had absolutely no problem with Zelda's controls after 30 minutes with it. My girlfriend, who's only played 2D Zeldas, picked it up faster.
I have ET, CoD3, R:RR, SMB:BB, and Zelda. I'd say CoD3 is a damn good representation of what it can do. Rayman does the trick too, in more bizarre, less traditional ways. Wii Sports is just amazing, especially bowling.
I own a 360.
