Insomniac Games said a while back that it was "flattered" that the spherical worlds of Mario Galaxy were inspired by Ratchet and Clank. But Miyamoto says he's never heard of it.
Official Nintendo Magazine UK asked the father of Mario what he thought about Insomiac's comments in a recent interview, to be published in the next issue (Issue 25). But instead of acknowledging Insomniac's work, he asked: "Is it a PC game?"
Miyamoto said he was "surprised" by Insomniac's comment. "In terms of the spherical worlds and anti-gravity," he went on to explain, "we had the original idea as soon as we finished the development of Mario 64 and had been experimenting with it for many years, even on the N64."
