The game is easy to learn, very addictive, and extremely fun. Only the two analog sticks on the PS2 controller are used, along with a few others that serve minor purposes. You begin rolling up small objects such as erasers and thumbtacks, but by the games end, your "katamari" consists of buildings, giant squids, clouds, and even islands.
If you like innovative titles, or just plain fun ones, pick this game up. It's only $20! ROYAL RAINBOW!
It. Is. In. Sane. It's the best game EVER made.
The story is fascinating. The King of All Cosmos (or in other words, God) gets drunk one nights and eats all the stars. In an attempt to fix things before his wife gets back, he calls up his bastard son Prince(you) and tells him to go down to Earth and roll up anything he can find(including children)into a ball, which will then be compressed into a star. The King of All Cosmos is sometimes not impressed with your hard work and will yell at you and make you cry as you lay ready to die from exhaustion.
The King also throws up rainbows and thinks all of your cousins are disturbing.
