This is such a terrible solution to a literal non-problem. You should be able to make software that has a limited lifespan if you want. I just think that's fine. Games should not be special.
Think of your favorite movies. Now imagine your kids never being able to watch them. Same for books. Same for music. Games are an art form distinct from the above, and can in many ways be more powerful than they are. I've played games that toyed with my emotions in ways few movies can. As such, they need to be preserved just as all the above categories. I'm incredibly glad I can still play most of my 80's and 90's DO…
Moreover, if a game is art, it is a form of speech, no? And compelled speech seems like a moral violation.
