You can already do that! Contact the rightsholders and negotiate with them. It'll probably be relatively cheap to buy an EOL game.
>Nobody suggests to lower the prices... Do you even understand what SKG is about?
I'm not misunderstanding anything, you are failing to consider basic economics.
Making the product last longer is effectively indistinguishable from making it cheaper in the context of the EU.
But I do get why a bunch of people seem to dismiss SKG as "childish". I didn't start from that point of view, but the commenters here certainly have me convinced with their tunnel-vision.
