Hm.. Well.. For Natal I have two ideas, one of which will never happen, and the other, probably only for fans..
First one, Pokemon. Yea yea it will never happen, but, imagine:
Do pokeball throwing motion and yell: Charizard I choose you.
*charizard pops out*
Say: Charizard, use flamethrower
See flamethrower on screen.
Hold out hand: Charizard, return.
Would work perfectly don't you think?
2nd one is, Harry potter. Use anything as a wand, and do basically any motion, and saying the spell.. Seems boring to me, but some people might like it.
Other than that, best I can come up with is, head tracking.. If you don't know what I'm talking about, check this out:
