I loved Fahrenheit, so was looking forward to Heavy Rain. The demo, though, was just a little disappointing. It’s all very depressing, seems to mostly consist of barely-interactive cut scenes and the one action scene in the demo went on for so long as to become quite funny. Also, the visuals are nice but dim and the voice acting it all right by video game standards, but not good enough for the moody noir feel the game seems to be going for.
I’m intrigued by it all, but the demo didn’t sell the game to me at all.
