This is a reasonable conclusion. It's a case about reselling of license to programs like maya, games, movies, etc. So if this goes through for autodesk, it would naturally hit games. Besides games has been the center of cases recently, can you see it skipping on this when companies are going crazy over these things?
I honestly don't think that would happen, though. If you think of a place like GameStop, they make tons of money from used games, so an enforcement of this ruling could kill the chain eventually. But I don't think publishers would do this, because this would be a huge impact on their new game sales, not to mention all of the negative publicity they would get. They have to be making tons of money through GameStop with sales and pre-order sales of new games. I just seems to me that killing off used game sales completely would be suicide for publishers. Instead, I think they'll just keep nagging and preaching to consumers like they have been.
Not to say this ruling doesn't worry me, though. If used game sales would be outlawed, that would give publishers even less of an incentive to sell new games at a discounted price if they have been on the shelves for a long time. Less competition. Also, what would happen when a game finally gets removed from the shelves if it isn't also released digitally? Does this mean I can't buy the game, ever? I don't like the potential of this.
