So, I finally played (and finished) the original Katamari Damacy the other day. It was quite disappointing next to We Love Katamari. One of the big features I was looking forward to were the Eternal levels, but I didn't realize that there were actually a finite number of objects which I could roll up, hence making the level completely worthless. The 'Make a Constellation' levels were also bland compared to the various special request levels in WLK (The Sumo level is one of my all-time favorites).
I also bought Knights of the Nine, but I haven't installed that yet (or played Oblivion in a while).
