Is it even legal to do that?? If its not its very unethical to just kill a game after 3 years and expect no one to complain.
If the "licensed not sold" tactic has failed, which is the case in 99% of software sales, consumer laws apply. The exact laws are too different between countries under .nl laws I would send a nice letter:
"Dear Epic Megagames, your product is covered with a hindrance that should not be on it. Taking the civil law, book 7, article 20, into account I demand the you immedeately remove this hindrance. I await your decision about this within two weeks, and within the same two weeks, I expect the product with the hindrance removed, or, a planning by you for removing the hindrance. I you fail to comply I will invoke my legal right to reduce the price of the product and get part of my money back, as it has become completely non-functional and I believe a game is interresting to play for much longer than 3 years I think a reduction of the price by 50% or more is reasonable".
If the "licensed not sold" has succeeded you cannot invoke consumer rights since there has legally been no sale between a merchant and a consumer. Your only defense can be the license itself, if it has no time limit, you can try to defend you with a "breach of contract". If the license has the time limit there is little you can do. This is why consumers should always strongly resist EULA's, the mere fact of a "licensed not sold procedure" means your rights are completely gone.
