While it is a katamari game in spirit and look, the feel of the game lacks due to the limitations of one analog control.
The graphics are decent enough but rarely does the game move fast enough for any rendering. The look is simple and blocky with a bit of quirky spin to see the realistic object in a cartoony setting. The colors are bright and the graphics are decent but the katamari games never sported the most updated graphics. The sound is much better but the tunes are recycled from the previous games. If one was fine with the music in the previous games and still finds the music enjoyable then they should be fine. Otherwise, the music varies from grand score with lots of bells, whistles, and the allusion to an orchestra to a humming of a tune.
There are many things to collect but the levels tend to repeat over and over again so the replay value is next to nill once completed. Then again, one of the reasons for most katamari fans is to pick up every object, present, and cousin available and the game does that well. The only problem is the redundancy of the levels, which might hamper on the freshness of the game and may seem repetitive after finishing the game once.
The multiplayer is more of the same as the previous titles and this is a game best played by oneself if one would like to collect everything.
While I loved the PS2 titles of the game, I just cannot wholehearted recommend the game due to the controls, the recycling of levels, and the lack of multiplayer. While there are redeeming qualities like the collectibles, quirkiness, and the ability to choose tunes during a particular level, the game just does not come close to quirkiness of the first two. This is not a the game to introduce a new player to the franchise, but might pacify enthusiasts before the next one comes out.
