I've noticed on sites like Amazon and Play that allow people to sell their games, that there are lots of people selling secondhand console games but for some PC games there is no-one selling them. Is it that case that PC games cannot be sold secondhand due maybe to some use of CD Keys or registering the game to a steam account (for example)?
I have always thought of PC gaming as being cheaper (software wise) than console gaming but this actually makes it more expensive.
