The Katamari games are great if you've never played them

I haven't... I usually like these kind of weird games, but all the trailers I have seen never attracted me. Well, I think it would be better to say, I have never really understood the game. Maybe I should look at some gameplays.

The gameplay is great, you're just a tiny little alien rolling around a ball that picks up objects it rolls over; as your ball grows you go from picking things up like thumbtacks and other small objects all the way to picking up entire cars and buildings. Also you can pick up live animals and humans and watch them panic, its great. Overall its just good fun, there's no real plot or anything
