Correct me if I'm wrong, but doesn't this ruling just mean you have the RIGHT to resell digital games? Having the right to do it and being able to do it are two different things. Does this ruling force digital publishers to make it possible for the games to be resold? Or it just a symbolic ruling that has no practical effect?
Its just like how consumers have the legal right to make backups of discs they own, but that doesn't stop the disc makers from encrypting the discs or whatever which makes it either extremely difficult or impossible. So even though you have the RIGHT to make backups, you might not necessarily be able to do so and the disc makers are not obligated to help you do that. Figuring out how to do it is your problem, and if you can't do it that's also your problem... again you have the RIGHT to do it, but that doesn't mean you can do it technically speaking.
