If Valve or EA want to sell games in the EU, they better learn to abide the law, or else.The Court of Justice of the European Union has ruled that publishers cannot stop you from reselling your downloaded games.
More specifically: "An author of software cannot oppose the resale of his 'used' licences allowing the use of his programs downloaded from the internet."
The Court said the exclusive right of distribution of a copy of a computer program covered by the license is "exhausted on its first sale".
The ruling means that gamers in European Union member states are free to sell their downloaded games, whether they're from Steam, Origin or another digital platform - no matter what End User License Agreement has been signed.
The ruling continues: "Therefore, even if the licence agreement prohibits a further transfer, the rightholder can no longer oppose the resale of that copy."
The ruling suggests that if you've bought a license for a game off your mate, you're within your rights to download it from the publisher's website. "Therefore the new acquirer of the user licence, such as a customer of UsedSoft, may, as a lawful acquirer of the corrected and updated copy of the computer program concerned, download that copy from the copyright holder's website," the Court said.
Whether Valve and EA will make changes to their websites to reflect the ruling remains to be seen.

Essentially, the court held that, under EU law, the right of software developers to control distribution of a piece of software – whether stored physically or digitally – is "exhausted" (i.e. lost) once the developer has been paid for it (known as a "first sale"). This means that developers lose the ability to prohibit any second hand sale.
However, if a second hand sale goes ahead then the first purchaser must stop using her copy of the software and render it unusable, because the developer's right to control reproduction of software is not exhausted on a second hand sale. In order to make sure that the first purchaser stops using the software she has sold on, it is permissible for the software developer to use "technical protective measures such as product keys".
