Just because people use Steam, doesn't mean they're all happy about it. I know a few who never wanted to ever go on Steam but were forced to do so to play Skyrim. Given the choice, they wouldn't be a part of the million who play on Steam everyday. So there is fault in your logic that just because someone uses a forced service that they're a-ok with it.
Also, the EULA is written in a way that you could read it as a secondary clause that keeps consumers from reselling the game as their own. I don't own the rights to the game just because I own a copy of said game. I understand this is applied by the copyright laws, but I fail to see how anyone can tell me that I paid them for the cost, plus extra, for a product and yet they retain the right to take it away at anytime. You can't sell me a car and then decide later that it's outdated or you don't like the way I'm using it and then take it away from me. If I'm not breaking any laws - running people over with it, using it in a bank robbery, etc. - then you have no grounds to take my property away from me.
I'm extremely disappointed to see people so nonchalant about the whole deal. They are retaining the rights and posession over YOUR stuff. You shouldn't be ok with that.
People are getting confused. You don't own the game itself and it's content. You own the license to it, to play it, and to do whateve ryou want with said license to said content. Otherwise people would claim to be able to own donald duck or mickey mouse or gods knows what other things. So no you don't own that content, just the license to watch it. So you can still or should still be able to sell it. I mean the license was covered, who cares who gets it? Right? Not you since you've sold that disc. Also you own the physical disc as well.
Copyright ownership of stuff on disc = Nope.
License to view stuff on disc = yup, you can do whatever you like with it. Your license, there's no requirements to obtaining it other than buying the game and agreeing to the eula which may or may not be enforcable depending.
Physical disc itself - yep. Again do what you like with it.
I'm just posting to clarfiy this, as some people seem to be unaware of the difference.
