Just got Heavy Rain last night and played around 5 hours and couldn't put it down. Gotta say i think this game is such a breath of fresh air but i think people will either love it or hate it.
I just read their plansd for the DLC and how it will feature a background chronicle for characters and i think this sounds a great idea, so please let me know - do games like this have a place in the current market, will it be a success and did you personally enjoy it or not?
