You forogt to add "trackmania" between "Mario Kart" and LBP". Unfortunetly it looks like all the racing is course-only, IE MK, instead of checkpoints like TM which means you can make those mountains for show but otherwise they're useless. No huge-ass adrenaline jumps over them or something like that, just the follow-the-line-or-inexplicably-warp stuff.
Still, if they do it right it could be awesome. Sony is doing what Ninty should've done a long time ago.
No Dragon Claw? The most intense original character for MUGEN (As well as the only 3-D original character for it) could link any three of his four special moves into a massive combo and when done successfully the third super would get souped up and become a computer-crashing spectacle of flaming particle effects.
