This is the perfect Katamari experience...
...almost.

This game's main draw is that it compiles stages from the previous games in the series into a delicious little collection.
This, in and of itself is really great, but the game does have some drawbacks.

Mainly, the lag is really bad at times. The game can really start to chug when a lot of items are on screen at once. This doesn't happen often enough to become a severe problem, but it is an annoyance.
Moreover, the remixed songs aren't as good as the originals, in my opinion, and I think that the 5cm Prince Remix of Katamari on the Rocks is downright awful.
The new prince-hop would've been a great addition, if it weren't for the fact that it barely works half the time when it really matters. When it eventually does decide to work, the delay between you doing the motion with the controller and the actual hop is insanely long. This could've been fixed by having an option to map the move to one of the unused buttons, instead of being forced to use motion controls.

Despite all this, I can easily sink many an hour into this game without getting bored. Katamari Forever manages to be that great despite its shortcomings.
