Haha! Really? The publishing industry fought it all the way to having to have a law (copyright act of 1976) made to explicitly allow resale. The music industry fought it and managed to disallow music rental. The movie industry fought it, but lost the rental market too, although they managed to claw back some ground by clever agreements with the rental companies. In 1998-9 they tried introducing a DVD format you couldn't really resell, called DIVX. Luckily, it failed dismally.What I don't understand is why game publishers think their particular industry should ban used sales of physical media, when even the music and film industry, who are far more aggressive on IP and copyright issues haven't been campaigning for this.
The used market has long been a target of all sorts of copyright based companies.
