Age of Empires 2, despite being Microsoft owned, is easily one of the best strategy games of all time and has very clearly stood the test of time. It’s over 25 years old and people kept playing it a lot even before the HD remakes. I remember reading that the folks that made the 1st game often had to choose between “actual history or hollywood history” for some details, often going for hollywood because it made for a more fun experience.

I suspect Factorio might stand the test of time as well, and it’s clearly something made by someone who really understands the medium. I haven’t begun my factory yet.
