A pre-alpha title called Motion Fighter used Sony's PlayStation Move motion-sensing controllers to facilitate one-on-one street fighting at their GDC press conference this afternoon.
A demonstration we watched had a person swinging his fists -- both loaded with a Move controller -- to beat down an on-screen thug. The motions looked to be on a 1:1 basis, with the on-screen fists of his character seeming to connect perfectly in line with his real world movements, but they didn't seem to connect at the expected time. At the end of the presentation, the player took the on-screen enemy into a headlock and hit his head in.
What Sony showed was marked as "pre-alpha," which they estimated as 20 percent finished.
