ya i heard of it before...it sounded incredibly weird, but at the same time super fun...just so you know, the fact that you have 1 of his moves similar to olimars pikmin throw, makes me super happy, he would be the closest think to having olimar in PSAS!
I got "Katmari Forever" for ps3 (essentially a best of collection of the previous games) for $12 on amazon. totally worth it. "Me and My Katamari" is on psp but i heard it doesn't have the best controls due to there not being dual control sticks on a psp. "Touch my Katamari" came out for vita and heard it controls much better. "Katamari Damacy" and "We Love Katamari" are the first two games and theyre on ps2 but i'd just spring for "Katamari Forever" on ps3.
You play as olimar in brawl? that's awesome. i've only ever met one person who's good with olimar. My two best characters are DK and Snake
