I think a kind of fencing game would be pretty cool, in which you turn the crank forwards to lunge forwards (maybe you only actually "strike" after a full turn, and the rest of it is just moving forwards) and jump backwards when you crank backwards. Would be especially cool if it were from the first person perspective (of course something very basic in terms of style, like vector tanks or something)
Really regretting cancelling my preorder now, I wanna make that :(
