The game makers are selling a brand new experience, which when bought and consumed fully by a customer, can then be sold on as a product that is identical to the experience the original makers are still trying to sell. This is a pretty unique situation for an expensive (some would consider luxury) item.
I'm not advocating the course of action the makers of Heavy Rain, and other studios, have taken and I fully agree that we should be allowed to sell on items of our own possession! But maybe consideration should at least be given that this issue is a little different to buying and selling traditional products second-hand because of the nature of the media and its price bracket.
Oh and I used to tape songs from the radio as a child in the 90s
P.S. Saracen while the manual may not be in the best condition, I hope the game experience is ultimately the thing you decided to fork out your money for!
