Interesting to hear Miyamoto being excited about HD graphics. I thought those didn't matter? How funny would it be if Nintendo's devs were inspired by having superior hardware? If after all this talk about motion control being the bee's knees and how HD doesn't matter that THAT, not motion control, inspires them to make their best games in years?
What dev could honestly find it exciting to work on something like Wii Music? How could that be a satisfying outlet for one's creativity? The whole style of the Wii Series is anti-creativity. No characters, no art design, no story, no setting. It is literally generic avatars doing real-world activities. A game designer wants to create new worlds. That is what inspires him. It is the difference between writing a novel and writing a manual.
