Netflix could make the argument that "you're paying for the access, not to keep" and that's a fine argument, but that's also not a service i'm interested in.
there's also a bigger conversation here about game preservation as a whole, or even further: the preservation of art. i don't see how Cozy Grove 2 can be truly preserved if it's behind lock and key with the initials NF on them. i've had this concern about MMOs as well, and as such am a huge proponent of private servers.
