Katamari Forever is the fourth console game in the Katamari series and the sixth including a version for the PSP and iPhone (another reason to want an iPhone). In this game, you play as the tiny green prince, whose enormous father, the King of All Cosmos, has been knocked on the noggin by a passing meteor and fallen into a coma. You and your intrepid band of cousins build a robo-King to replace him, but it has ... issues ... and destroys all the stars in the sky! In the end, it's up to you to restore the cosmos.
How do you do this? A perilous quest, maybe? Oh, no. That wouldn't be any fun at all! No, you rebuild the cosmos by rolling around a sticky ball. Yes. The more you attach to the sticky ball, the bigger it gets and the bigger the items you can stick to it. When you start, the ball's only a few centimeters across and you can only pick up things like thumbtacks or earrings. Eventually, you work your way up to things like shopping carts, whales, and buildings. When you have a big enough sticky ball, it becomes a star and you start all over again.
Go on, tell me that doesn't look like highly addictive fun.
