I'd love to see a keyboard-screen control system, as is to be expected on a PC. Drag screen to look, and use left hand for forwards-back, maybe strafe, a la wasd. Firing could be tap, as opposed to drag. Jump can be either a key, or, skin me alive for saying this, forgo jumping.

Many games are doing fine with no jumping. Mass Effect, SWAT. Can be idiotic at times, but with a game designed around no jumping, it doesn't even register.

Oh, and, even on resistive, firing could be 2-finger. Very fast swiping to the right could be fire, via gesture. Or a key near forward, with small keys one could just lean the finger outwards, from W to, say, E.

I think it's possible to have this on N900 (I don't mean it can be done, I mean we might just see it).
