So the added "value" that's supposed to justify an extra 20$ being tagged onto the price here is basically the SFIV equivalent of Resident Evil DS's Master of Knifing mode, done with motion instead of stylus taps/swipes.
Yeah I'm gonna sleep on this for now until more content is added.
Apart from the move to a seemingly more sterile audio/visual design and the sheer amount of negative reviews for the PC version currently, what is here doesn't seem worth the asking price and overall it just seems rushed/unfinished.
