Go watch Acursed Farms' series on the matter called Dead Game News. Ross covers this topic brilliantly, he will hit some his random game reviews with Dead Game News segments, like his Division, Trackmania, The Last Stand (although seems the devs finally listened and made a steam version) and some others. This has been a very serious topic for us for years. In his video "Software of my dreams" is basically a ninja ripper for games as a service open worlds, so they can be collected and archived etc.
