That's spelled Katamari Damacy. That's the original on the PS2. The sequel on the PS2 is We Love Katamari, and the third sequel, for the Xbox 360, is Beautiful Katamari.

I actually prefer the first one out of all three of them. They are all brilliant, but yeah.

And, for the 360, you can't go wrong with Orange Box either.
