Personally, I think a major rewrite of copyright laws is necessary. If I were in charge of it, I’d make it so that copyright protection isn’t given by time, but rather conditionally alongside distribution. Basically, you can copyright your game forever, but that also means you have to distribute it forever such that a reasonable person can obtain it legally, and the moment you stop doing so, you irrevocably lose that protection and anyone else is free to distribute it however they like.
