I'm not surprised his words caused uproar, it's frustrating reading his ideas and comments on the industry more often than not.
The F-Zero control scheme rubbish, the 'until we have the right gimmick for the next game' train of thought, Mario Galaxy 1 was a disappointment, the direction he takes games in, and now 3D camera's being too hard...
Super Mario Bros. NES was hard as nails, as was Super Mario Land etc... so he's wrongly referring to 2D Mario, but instead referring to the dumbing down of 2D Mario with excessive lives, tutorials and guides.
I wouldn't really be interested in another Galaxy, after I didn't much enjoy the more if the same in Galaxy 2, so whether we get that or not I don't mind... but this idea of settling on a middle ground and not pushing is just frustrating to hear.
Oh well, I'll just have to get my kicks from other platformers like Tearaway and Ratchet & Clank for the time being.
