A video game, when purchased on a disc (physical medium), is yours. You are free to do whatever you want with it, including reselling it. This is not the case for dematerialized video games, those sold in online stores, Steam in the lead on PC. Once purchased, the game is yours (well, as long as the seller and provider of the user rights exists), but it’s impossible to put it back on the market. A clause is generally opposed to it.
On October 21, the Paris Court of Appeal decided to invalidate this ruling. For example, the clause is legal. Indeed, the Court took into account the fact that a video game is not only a simple software, but also an artistic work subject to copyright. And in this case, the introduction of a second-hand market is likely to harm rights holders.
Patatras and back to square one.
