MTV's Stephen Totilo has posted the third and final part of a lengthy interview with Shigeru Miyamoto. Though the bulk of the article was lent to discussion of Wii Music, the pair broached other subjects, including what Miyamoto perceives as a lack of innovation in titles such as The Legend of Zelda: Twilight Princess and Super Mario Galaxy.
Though Twilight Princess was "not a bad game," Shiggy felt there was "something missing," and was also semi-criticial of the previously untouchable Galaxy, which he thought was "very new and [...] very unique," but "somewhat conservative in terms of how far we branched out with design." If we may mount the Wii Fanboy soapbox for a moment, we'd concur that Twilight Princess was far from being the best Zelda, but found Galaxy to be consistently creative and entertaining.
Elsewhere, Miyamoto referred to the "next Galaxy," which may or may not mean we'll be getting another Mario-in-space game (we wouldn't read too much into it), and that he loves Portal. Nintendo fanboys we might be, but we can probably all appreciate that last statement.
