"Holy crap. This is how all platform games are going to be soon, and it is going to be awesome."
Too bad next to all of the current platformers nowhere meet the "acrobaticness" of Mario64 that made it what it is, all I see are platformers with guns, action games pretending to be platformers, and platforming using the same damn wall-based maneuvers over & over & over & over...(I'm looking at you Prince of Persia:SoT)
I think one of the main problems with Sunshine was that the old setup used in Mario64 just didnt work, having to repeatedly get sent back to the town hub each time you collect a shine is retarded, even though the levels are setup differently depending on the shine objective you select to grab.
Here's to hoping the "New Super Mario Bros." for the DS does well, as it's really shaping up from the videos I've seen.
(2d platforming using 3d graphics & nice use of a physics)
[EDIT] As for the butt sliding up to the last bowser stage, I believe that is actually doable on the real system if you got a 3rd party controller with a turbo button installed.
