Heavy Rain

To buy or not to buy? Just played the demo and so far it looks and feels pretty epic. The demo was a bit slow but if the story is excellent it's worth it. The fight scene was cool, not just the standard QTE most games are using and the 4 main characters(a CSI druggie, asthmatic PI, emo father and some reporter chick) have interesting stories. I have been waiting for this game for ages and I really hope it doesn't disappoint.
