Katamari Damacy is certainly a unique video game. The basic plot is that the King of All Cosmos has knocked the stars from the sky. You, the Prince, must roam the earth rolling up objects to replace the stars in the sky. Your katamari is the ball you roll in front of you. When it rolls over something small enough for it to pick up, that object sticks to the katamari, and the size of your katamari grows.
And so each level places you in a room or city with tons of "stuff" strewn about. You can roll up everything from pushpins and bananas to elephants and small islands, depending on the scale of the level. The star levels give you a katamari size goal that you must achieve in order to advance in the game. In the constellation levels, your goal is to gather an item related to the constellation. So when creating Gemini, you must roll up twins with your katamari, and when you're creating Cancer, you're looking for crabs. Some of the constellation levels ask you to pick up as many as you can, while others ask you to gather a single object, and the goal is to find the largest one. This may sound easy, but it actually means avoiding all objects of that type while making your katamari large enough to grab the biggest one. I'm not as big of a fan of those levels because I find them frustrating. For instance, when creating Taurus, you must find the largest cow possible. But there are cartons of milk and cow-patterned objects in your path, and those count as cows.
For an added challenge, presents from your dad the King are strewn about the levels. You can also unlock special endless levels if you create especially large katamaris. You can also return to the constellation levels as many times as you want to try to improve their size. So while it won't take a huge amount of time to play through the game, there are lots of opportunities for continued gameplay.
My only problem with the game is that my thumbs start to hurt after extended playing because the game uses the analog sticks exclusively.
This game is great fun, with amusing dialogue from the King of All Cosmos and memorable music. I'm not much of a video game player, but I'm definitely a Katamari Damacy fan.
