What I think it's harder to preserve is the fact that modern games are often constantly updated with new content to the point that sometimes not much of the original experience remains. For example Terraria 1.0 is wildy different from 1.4 released almost 10 years later and this can be said of most modern titles, especially ones that were released in early access. Not to talk about online games, titles like Fortnite, Warframe, Destiny to name a few are all constantly evolving with new content releases that alter basically everything. Good luck preserving and replaying some specific updates if you ever feel nostalgic about it.
