Of course the frame rate is awesome... in case you didn't know... the DS hardware has this little "quirk" that forces games to be 60 fps, unless the hardware is rendering full 3D in both screens at once, in which case it's 30 fps.
But anyway, I just thought of an great use for the touchscreen...
You know how on the bottom screen it has a list of all 8 racers? Well you know how some items like red shells home in on people? Well how bout you pick who you shoot?
Other than that, I'm guessing tapping the map will change map modes.. I've seen both an overall track view, and the zoomed in birds eye view of the action....
8 player wireless, just as I though. Now all that this needs is wireless confirmation. Mario Kart on GBA was sweet. This looks to take the best of all previous games...this will be the ultimate mario kart...
EDIT: Oh and I really hope more Nintendo characters are available.. just for fun
I wonder if exclusive items will be back. Either way, Diddy Kong must be in this game. I'd love some new surprises too, not just the "famous" Mario/DK people.
Paper Mario 2 and SuperStar Saga had new characters...how bout some of them?
