While Beautiful Katamari is highly addicting, the shortness of the game takes much away.
Beautiful Katamari is funny, addicting, but all too short. The nutty world of Katamari is entirely charming and will have you scratching your head wondering just what was going through the minds of those that created the game (not in a bad way, of course). You play as a sprite, the Prince, who is ordered by his father, the King, to roll up objects that will turn into cosmic bodies. Sometimes the ratios are off, and some objects are seen as larger than others in the game, but still, I could spend hours rolling up my ball to the size of Jupiter in just precious few minutes.
The King will tell you with each mission to roll up certain items (such as cold items, ritzy items, etc.), but this aspect of the game is purely optional, and more for those that wish to master the game score-wise. As long as you enlarge your Katamari to the specified time within the time limit, you're golden.
The dialogue in the game is purely entertaining and insanely quirky. The entire plot is very strange, but its what gives this game it's charm. Unfortunately, the length of Beautiful Katamari severely takes away from the overall game. Within only a few short missions, the game is finished. The only way you'll get more out of it is to do "side missions," such as finding the Prince's cousins or rolling up presents (which are accessories to decorate your sprite). Playing the game straight through would only take a few hours to complete.
If you're looking for something different and casual, I would strongly recommend Katamari. While fun, this game was clearly not meant for much replay.
