You should definitely pick it up, just don't expect much replay value. Almost all of the mini games featured are the ones from Mario 64 DS, and I found the game way too easy in general. If you want to fly through to the end as soon as possible without finding all the coins or alternate routes, the game will be over in a day. Getting 100% can take up to a week or so, but after that, there isn't much of a reason to play it anymore unless you've got a buddy to play wireless with.
@QS: The new 3D graphics would have been bearable if they would have left the challenge intact. I still would have preferred an updated Super Mario World look, though.
