“For the most part up until now on a single console we haven’t made two games in a single franchise. But when we first made Super Mario Galaxy for Wii it was the first time we really experimented with the spherical worlds. We had a lot of things we were interested in doing and a lot of creative freedom that we had in that world that we were interested [in doing]…[The original plan was to] essentially create new variations of the worlds in Super Mario Galaxy…There’s something that might be kind of a little bit ghost like but still a little different.” – Miyamoto
Miyamoto went on to say that the developers of Galaxy 2 had so many ideas that about 90% of the levels in the game are original. The other ten percent are levels from the first game, but with new objectives.
