I love Katamari Damacy, and those who don't are strangely off. I picked up the 360 version as one of the first games when I bought that glorious fun machine six months back.
I've finally found a bit of time to get into it, and it is much more of the same stuff, but improved in a few key ways. Not everything is about getting as big as possible in a small amount of time. The most memorable one I've come across so far is one where I had to get a Katamari up to ten thousand degrees to make Mars. And there were plenty of things to run over that would cool you down.
The only real complaint I have with it is the King is never satisfied with my work. This is a throwback from the other games as well, but he's a bit more insulting towards the prince this time around. He asks for six meters, I give him ten, but I still get boos from the crowd and he tells me how bad I am at the game and gives me points and a sound byte that conveys disappointment. This has caused me to yell at the TV on a number of occasions, but I've been disappointing people for years, so I manage to get over it and move on.
All in all, fun game, great to play while drinking and another wonderful soundtrack that I can't play in my car because of the property damage I cause hitting mail boxes.
