It's a brilliant sequel to one of the most creative titles ever, and about as close to perfection as you can get in video games.

It's not very good... The weapon balancing is really counterintuitive, the units are not that interesting, the maps are bland, and the story is laughably bad.

It's just a good game. Characters are interesting and maps are fun.
I don't know if the story is any good since I'm skipping all the cutscenes but that bit's not important anyways.

This game was a huge disappointment.
Goro the Slacker's story is cool though.

It's disappointing compared to the first game but still quite good.

Controls are not so good, and there are very few levels.
The game gets extremely repetitive by the end.
However, since it's a Katamari game it's still quite fun.

Didn't play the singleplayer campaign but the multiplayer's pretty good.

It's a very easy game to break. Difficulty becomes a joke once getting the child units, but it's still quite fun.

The gameplay's really good!
Most of the maps are "defeat the boss", but it's surprising how each one is still very enjoyable, memorable and well-designed despite its repetitive nature.
