I just purchased and played through Heavy Rain this afternoon. I'm not sure what genre it would qualify as. I mean, it was little more than an interactive movie that was actually a pretty bad movie and an even worse game. In spite of that, I suspect it will remain memorable in spite of fairly glaring oversights in the narrative. Were I to pigeon hole it, I'd probably say it most closely resembles an adventure game but there were no real puzzles, just a lot of hand dexterity tests.
