All the multiplayer games that are delisted should have their server data turn open source, in order for the games to still be playable.
All the games generally that are delisted should become public domain so they can be preserved and be accessible to those who paid for them.
the kind of shenanigans that you "rent" a game by paying on Uplay and other platforms is ridiculous.
"You will own nothing and you ll be happy."
All kinds of digital data are headed towards the end of there is no ownership.
