I must say I'm disappointed- the 'box version is actually not as good as the Dreamcast original. There are some elements of the graphics that are more detailed, but the look is blocky and the chicks look vaguely creepy. Worse yet, the controls, while not 'loose', aren't nearly as tight and precise as the DC Soul Caliber.
So far I've only played a few hours, but I'll report back once I get a chance to play one on one against another player.
