That's what I gathered from my short time playing the game. Frame rate was a bit low, lagged a bit. I had no idea about the controls other than top shoulder buttons charging your heart gauge really, so I didn't really get the full experience. I was just happy getting Joseph to use his machine gun.
The taunts are fantastic. Old Joseph has a great one relating to Josuke's hair.
A cinematic JoJo game would be too good for this earth.
