One of the things that sold me on Glitch was the news about Katamari author K. Takahashi joining the team to add his special weird world view to the game. Yet, no further news came out after that, and whatever input he had in the game was obviously well blended in the team's style, so that I never managed to point out something specifically Takahasian in Glitch.
My question is: is there any way we'll ever know which concept were invented by whom, and what was discarded? It should be really interesting to learn the different personalities and game design styles of the single authors, and the process through which their ideas become part of the Glitch experience...
