Unfortunately, it was upgraded from buggy and boring to just boring. I can't think of any reason why you would want to get this game instead of Soul Calibur. The main problem is, I can't really say where they went wrong. All I know is that this game is not very fun at all, and everything it does, Soul Calibur does better. The arcade VF3 has a smooth feel to it, the fights almost look like a dance.
Every move flows into the next, and it is a blast to play and watch.
For the DC version, they cut the framerate, resolution, and sounds, and simplified the backgrounds. What is left is a stiff and uninspired shell of a once beautiful game. Avoid this game like the plague. There are far better fighting games available for the DC, Soul Calibur chief among them.
