Heh, I'm so looking forward to this game, as rumors have it that it will be released in the USA later this year.
Katamari Damacy's concept alone deserves an award, as it's probably one of the most unique concepts ever in the past year or so--you play as a tiny alien prince who's tasked to roll up a giant ball of junk. It's similar to rolling a snowball, which gets bigger and bigger as it picks up snow, only instead of snow, your ball is made up of assorted objects, even people!
Controls are supposed to be excellent, as you use the 2 analog sticks to navigate your growing ball of junk across the game's various environments. Hopefully we'll hear more news of this addictive puzzle game from Namco at E3 soon...
