“Plays are ephemeral and should really be enjoyed in the now. Even if you can perfectly preserve a play, and the means to perform it, tastes change so quickly in theatre that a play that’s entertaining today might not be enjoyable even a year later.” - you, in the 1620s, probably.

Now imagine that the play cannot be altered (game build), it can only be performed on a specifically shaped stage (hardware requirements), actors can only be replaced by lookalikes (‘remaster’ tweaks), it can only be performed with a full theatre (online requirements), and the playwright retains the only copy of the play (source code).

Then you start to approach the problem that is gaming.

Which is exactly why more needs to be done by governments to stop this. A simple fix would be to say that in order to qualify for copyright protection, a national archive reserves the right to request a functional copy of the work in a form compatible with any future data migration projects.

People have been altering plays for ages without much issue (just look at the mod community), emulating and porting plays to different stages, and even reverse engineering their own copies of the script.

The only real catch has been online stuff and even that is sometimes worked around or recreated. It's not an impossible task to solve the problem of making games playable into the future, but it'll probably require legislation to force game companies to preserve their game and server code to allow for it.
