Takahashi chose to theme the sequel around supplying fan service as a response to the significant support from fans for the original "Katamari Damacy". This stemmed from Takahashi's gripe towards defining games with traditional methods, such as displaying product descriptions on the front of its cover art. The development team chose to name the sequel "We Love Katamari" in reference to this concept, as well as the level structure focusing around taking requests from fictional fans. Takahashi noted that such concepts would have been impossible to implement in "Katamari Damacy" due to it being an original project. "We Love Katamari" was designed at a larger scale compared to the first game, and possessed a larger development team of 30 people. Takahashi mandated that it had to keep the spirit of "Katamari Damacy" while feeling new at the same time.
