Thank you for stating that. See guys, you should be greatful that we even have a Soul Calibur V. The series technically was supposed to end after SCIV, but due to the petition on (I believe the creators twitter), they decided to create SCV. We may be in luck because in some video, a few of the developers did state they want to continue making Soul Calibur games. If this game does well, then we can look forward to the series improving.
So what is the lesson? We should stop complaining and try to help the series survive.
If you really are upset at the lack of stories, you can always post on that thread to make your own endings.
