Keita Takahashi makes games that feel like "play". He doesn't really tell stories or ask you to invest in a world. Instead, he focuses on a central gameplay mechanic that's inherently unique and fun and crafting a unique aesthetic around it that enhances how irreverent and fun his concept is. It's all the strength of gaming as an interactive medium.

I could nitpick how some of the constellation levels are tedious, but that misses the point. Rolling a Katamari around and collecting ever-bigger objects is a joyful bit of interaction that no other game can capture. And it's backed by one of the best visual and audio aesthetics in the medium.
