Okay, here's the deal. I love SCIII to death, BUT it is extremely unbalanced. Like, seriously. It was not good for competition. SCII is like the God of Soul Calibur. It was pretty balanced (well, kind of) and it was quick. Moving was cool, and it was just nice in general. Hope this helps. :) Except for Step G though.

SC2 was also a lot of people's 1st soul calibur experience. so many people look at it with rose-tinted glasses.
