Same here. I love 3D platformers. Amusingly enough, I kinda could imagine a 3D platformer for Dragon Sparking proper playing a bit like a cross between Sonic Adventure and something like Devil May Cry or Platinum's other "Stylish Action" type games. (Kinda like Spark the Electric Jester 2, come to think of it...)
(I mean, most Platinum Games already have the soundtrack part down pat already. )
