I just finished the demo and I have to say...
That was absolutely terrible. The game is pretty graphically but that's about it.
The acting especially for such a experienced cast is stilted and lacks any emotion. The script itself is classic David Cage with slow, boring, robotic dialog and a poor narrative pace. With poor direction we're left with something that's just hard to sit through.
The gameplay is just as bad if not worse than Heavy Rain, the analog stick guessing game is annoying enough but stack on the button prompts flailing around the screen that vibrating non-stop and it's just a joke. The game takes no skills besides knowing where the buttons are on the controller, it's just plain boring to play.
Top that off with the same terrible tank controls and sickening camera sway that Heavy Rain suffered from and you've got one of the most disappointing things I've played in a long time.
Before you all jump on me, I loved Heavy Rain to death when it came out and I defended that game. But this is just a punch in the balls, it's like Quantic Dream has learned absolutely nothing from Heavy Rain's glaring flaws and just shit out an uninspired attempt to nail that "Interactive Cinema" feel. Something Last of Us beat them at while still maintaining exciting and engaging gameplay.
