When first I heard that Yoda and Darth Vader were going to be in Soul Calibur IV, I was more peeved that I was going to have to decide which version to get since Yoda was to be on the 360 version, and Vader on the PS3. Although the choice was easy (Vader > Yoda), I was still peeved that I wouldn’t get both. That’s how I felt when Soul Calibur 2 came out and I had to play with Link when Spawn was the character I really wanted (forget Heihachi, he was useless anyway).
I loved Link and, although I agree he didn’t fully fit-in because his bomb move and other similar moves, I still had fun playing with him. And Spawn has had many incarnations, one of which was Medieval Spawn. Having those two in the Soul Calibur world was a bit of a stretch, but not NEARLY as big of one as having Star Wars characters.
