I don’t think it’s unreasonable to want a game that I paid for to remain functional long term. In my case I have a copy of the Hitman trilogy in my Steam library, and as it stands when the servers for that game go offline it will become nearly unplayable just because the unlock system is reliant on the publisher’s servers. It would be easy for them to just release a patch as they decommission those servers to allow the unlock system to function offline, but right now there is no guarantee of that happening, nor any real reason to do so besides some consumer goodwill.
