Beautiful Katamari was the first time I recall seeing controversy about on-disc DLC. You had to buy a few stages, including the one they advertised the most that went from like 1cm to rolling up the sun iirc, and all the purchase did was toggle a key that allowed you to play the levels which were already in your CD. It's normal now, but at the time I remember people hating it.

For what it's worth I liked We Love Katamari (and the original, which I only played once the re-release came out) much more than Beautiful Katamari! They tried to mix it up in Beautiful Katamari where you not only needed to roll a sufficiently large Katamari, but also it needed to be made of specific categories of items, and while this is fun for a few levels it ends up being boring when they do it for almost the whole game.
