Katamari

This has to be one of the most addictive video games of all time... well in my opinion anyways. It's a game for PS2 and the basic premise is that you are the Prince of the whole cosmos and your father "the King of the Cosmos" accidentally got rid of all the stars in the sky, your task is to roll up things on earth to make more stars for the sky. The bigger the things on earth the bigger the stars in the sky. That sounds simple right? Roll up the world? Yeah you'd think that, but no! You have to use the two joysticks to control the Katamari (star) as you move around the very messy world of random junk that you roll up. So fun though!



I'm told that in Japan, where the game originates, games with an affinity towards collecting things are particularly popular, making this game a hit as in addition to rolling up progressively bigger katamari you can also work on collecting one of every object in the game! The game keeps track of what you have and what you need for you.

The best part is... there is a 2nd game!!!



This one is similar to the first, except it focuses more on the fans of the first game and Prince's cousins, each fan has requested that the Katamari be of a specific type or size so some are made of fire, ice, all cows, things like that.
