Yeah I prefer the DS version over Wii,
Wii version looks horrible in almost every department,
The graphics pretty much just an upscaled DS version, Hard to control the character (there is no sensitivity toggle - so I keep falling off), and forced 2 screen at the same time.
I must say the Wii version is basically an emulated DS version (DS emulator anyone?)
But the multiplayer, surprisingly easy between DS and Wii.
So I still say this game has pretty good multiplayer mode despite all of those issues.
