motion controls, will they ever appeal to the "core" gamers?

[KungKras]

Yes they can!

Just imagine a proper light saber game with M+ or Sixense.

People seem to forget that core gamers were pretty optimistic about this stuff during the Wii early years. But then the content never came, and industry propaganda and the content that was there hammered the terms 'motion controls' and 'casual' together.

Zelda SS had the chance to change that, but Aonuma's incompetence ruined it.
