Not the entire library, though. Games that aren't offered in any form anywhere, and also games that weren't localized (like Mother 3) shouldn't have copyright enforceable. It's either you give up production of the game or you produce it forever, no other sane way to go about it
I hate overzealous copyright prosecution as much as anyone, but I’m very wary of a model where you have to use something you own to maintain ownership.
There are things that work that way (RF spectrum), but in general I think it would cut against the purpose of copyright. I do think there’s value in giving creators exclusive rights to their own work, and making it contingent on distribution would hurt small companies more than big.
