The French consumer association is taking Valve to court. They argue that according to EU law (not just French), you own the game when you buy it, including any assets, accounts or other things you create.
And, since you own the games and account, regardless if it is digital or not, you have a right to resell it.
100% agree. If you buy something, it should be your property. This is how it used to work, until these corporate bloodsuckers changed it.http://www.vg247.com/2015/12/18/valve-sued-by-a-french-consumer-association-over-steams-subscriber-agreement/
