I had a play through of the demo of this yesterday afternoon - and man, this game is gorgeous.
The game looks as if it was specifically designed in a manner to show the 3DS as it's best. It really is gorgeous.
I found the camera to be a little difficult at first but then I got used to it by the end of the demo.
Same goes for the fun 'boosting' mechanic, I didn't get it at first but man, it's fun.
The demo didn't include any sections that allowed us to pilot a mech, disappointingly.
If Animal Crossing wasn't out soon then I'd be picking this up - but frankly, the 3DS Japanese lineup is TOO good coming up to Christmas.
