This is the same game as every other Katamari game. Nothing new. The most annoying thing is that the king talks to you while you roll the ball around and a translucent pop up covers the screen. You have to click a button on the remote to dismiss it while rolling around and collecting. And it happens over and over and over again.
I have been a fan of Katamari since it first came out and therefore I am obviously biased!
I like the new look of the game because the only objects your can roll are colored while everything else is gray. This does detract from the look of the game but it's very helpful when your trying to find items to roll.
Having spent some time in Japan it's very refreshing to find something so far off the beaten path. This is a great game for kids and grownups of all ages! If you find it just too lame... have a drink and give it a go later! Once you've got the walls spinning at home and in the game you'll have a blast!
