The comparisons between Tornado and Katamari Damacy are extremely evident, but there's one major difference: Katamari Damacy games are available outside of Japan, whereas Success's title has yet to accomplish that.
In fact, Tornado hasn't even released in Japan yet. It was originally scheduled to come out last year, but later become delayed indefinitely. Oddly enough, though, GameFly has a listing for a DS game called Tornado. Can it be the same game? Perhaps -- we hope so, at least. We wouldn't mind having a portable Katamari-like game release in North America for our favorite handheld.
Whatever this game is, it's being published by Ignition Entertainment and has a GameFly release date of September '08.
