In the future years when "study of video game history" becomes a thing, people will be able to examine and analyse old games like SimCity 2000 by actually playing them as they were. Since they have been archived and preserved by wide distribution.
Then as you get further into the future maybe you start to come across games where you have to say "sadly the only existing copy of the server code was lost in the great github fire of 2020, so all we can show you is this archived footage".
