I remember playing Wolf3D and Blake Stone thinking this whole game is great! …yet, there was more. Quantic Dream recently announced that they want to come up with a demo for Heavy Rain. They are just unsure on how to do it, what elements to convey; how do you let the gamer know what the whole picture is?"
