In this review, gaming Today's overall reaction was:
"Overall: Like the first game, I can't recommend this one enough…to the hardcore Katamari fans like myself. This game takes the same style and gameplay that we've come to enjoy so much, just with different levels and music to make it somewhat interesting again. Unfortunately, this time around you'll have to cough up $40 for this one. That may be cheap for a 360 title, but considering the first game cost only $20, this one doesn't feel like twice the gameplay. For those who have yet to sample this series though and have a PS2 lying around, I'd recommend just picking up a used copy of the first game. Trust me - and it pains me to say this - you won't be missing much."
