Interesting approach!

But that sounds almost impossibly computationally expensive for 3D games and the like. Furthermore most game inputs aren't discrete but continuous, making the problem even hearder.

Do you have a link to the paper?

They tested with Doom 3 and Fable 3. I don't recall the specifics but I'm gonna guess that the actions people take are really quite limited, so with a bit of work you can probably guess what they're going to do enough to make things playable.
