it will set a legal precedent that might be used against Sony, Microsoft, Nintendo...so they will make moves to comply with the law so they don't have a lawsuit on their hands
What a truly horrible notion and vision of our dark future.
You may make light of it now, and maybe Valve will go with the consumer friendly route of allowing for the resale of used games and keeping their service the same otherwise, but you can bet that MS, Sony, and Nintendo won't. Nintendo for example only recently started tying content to accounts instead of consoles, you really think they're prepared or willing to allow the resale of digital games?
Well, the only real option is to wait and see what they do, because clearly we're all at an impasse when it comes to argument.
