It seems the latest Soul Calibur doesn't have a two-player mode because it'd be trickier to milk players for money that way.

Yeah good luck with your single-player fighting game, Namco. I had some great memories with the original Soul Blade/Edge and can see why the early Soul Calibur games were so highly regarded, but as the costumes and breast sizes have grown more ridiculous I've lost interest in the series. It also seems that from a technical perspective there really hasn't been much advancement these last few installments.
Still love the weapon-based-fighter concept though, I wish another company would step up with something to take the series' place.
On a lighter note I'd like to mention that Angela's thread for Soul Calibur IV has one of my favorite titles of these forums.
