OH!! speaking of weightless animations... this just came to mind... and is completely off topic... anyone ever play/see atelier iris (sp) from nippon ichi? holy smokes do those guys FLOAT!
Yeah!
It disappointed me too! The stills looked so nice, and it was the first 2D game being developed for the newer home consoles I've seen in ages... an RPG no less. I guess I pine a bit for the ol' SNES-type RPGs, haha.
I suspect all the floatiness has something to do with Japanese culture...
