Motion Capture Or Animation For Games?

Thanks to TotalGames.net for their article discussing whether videogames should use traditional animation or motion capture to capture the movements of in-game characters. The piece points out: "One of the major problems with motion capture is the way that moves can sometimes appear disjointed and separated, as a character goes from one set of moves to another", but an advocate for motion capture comments that the process is "..a lot faster, as long as you can retain the subtleties from the point of motion capture to the raw data to the point where it reaches the engine." Can you tell the difference?
