Yoda and Vader in Soul Calibur IV. They are well known, iconic figures of their brand, and something could be said of their inclusion for the purpose of bringing fanboys from one thing to the other. Not this time. This time it's an entirely self-serving move that has roots in promoting the relatively unknown (to the the mainstream) The Force Unleashed.
The newest announcement is that the main character from TFU, Vader's "Secret Apprentice", will be a playable character in both the 360 & PS3 versions of Soul Calibur IV. Y'know, we just might've actually bought the inevitable DLC that will be made available for this game, but this move just really leaves a bad taste in the mouth. Just so long as The Force Unleashed doesn't end up using Ivy to showcase its physics systems we'll remain sane. Given the way things are going, we fear for our sanity.
