DRM is, but i think if it were to happen (unlikey given that the used video game and movie chains, as well as rental places), they would have to seriously lower prices to attact a lot of people. $50-60 is a lot to put down on something you can’t resell ever.
It also breaks a fundamental aspect of how the economy works in that non-consumables have always been resellable. This goes back centuries. It’s so ingrained into stuff that it’s a core part of economic theory. It would be hard to figure what would be the consequences if intellectual property was non-resellable, but I don’t think it would lead to more economic stability or long-term profits for most, if any, industries involved.
EDIT: A better business model would be for places like Gamestop which directly buy and sell used games to be required to give a smaller portion back to the company (not as much as they do retail %-wise, because that same game can go through 5 different hands at with no actual additional work on the game-industry’s hands involved). For sites like ebay or amazon where they collect fees, it could come from the sales of such items or a basic global fee that isn’t too high.
Another idea is to add a tax to the sale of any used game, DVD or book (hey why should they be left out) of say 10 cents (or 10%, whichever is less…) for each sale. For places like Ebay and Amazon, some other type of structure could be worked out since it would be too difficult to track down Bob when he sold a game for 99 cents to collect the 1 cent tax.
This would likely increase costs on consumer end, yes, but not majorly. It weaken any noise the industry has on after-market sales. While I don’t like paying more for stuff, if the gaming industry also is given some restraints on what they can do, i’d be for this, else, like anyone else, they’ll take it and demand more.
