My guess is that the format is really just a way to bundle the autoplay executable, and other "extended extras" found on the data track of modern audio CDs.
Good luck with the autoplay thing... It's outsky in Windows 7.
So, even if I do have the right to resell them, what good is it? I can't meaningfully exercise it.
Yes you can.
It's called gifting. I bought Half Life 2 when it came out, but later bought the Orange Box. It notified me that I had one extra copy of HL2 and I was able to give it as a gift to one of my buddies.
You can gift any game that you've purchased. Just have someone send you paypal, then gift the game to their username.
You can sell your Steam games. By saying otherwise you're just spreading FUD.
