One of the most interesting tech demoes during Sony's GDC keynote last night was a gritty looking game called Motion Fighter

The game's essentially a one-on-one street fighting title with a highly stylised look to it. Players use a Playstation Move controller in each hand to mimick their punches. The difference here is that unlike Nintendo Wii titles, punches actually feel responsive to the movements you make, rather than simple waggles.

The accuracy didn't look quite there during the on-screen demo, but there's certainly potential.
