I really liked the 2nd game, and felt betrayed that Namco made III only available on PS2 so I didn't play that one.
The graphics look great, however I didn't like the changes in the gameplay. It just didn't seem that fun anymore. The difficulty seemed unbalanced, and the modes weren't very addicting. It's not a bad game really, but it could have been much better in my eyes.
I really liked the trio of select characters in Soul Calibur 2. I loved playing as Link in the Gamecube version. However I didn't like Starkiller or Yoda. Star Wars is forced down our throats these days, and they're not that great at fighting in the game, and don't really fit the universe.
