There are millions of new gamers who buy into the industry every year who will never get to experience these games unless they have an older family member with an ancient console set up in their attic.
Yes, BUT
This is true for the majority of games on most platforms. There are millions of new gamers every year that will never play a damned thing from a 2600, a Colecovision, an Intellivision, an NES, a Turbografx-16, a Sega Genesis, an Atari Jaguar, a 3d0, a Saturn, or any arcade machine built from 1979 to 2015.
unless there's a relative with a stack of old ass consoles, his or her own arcade, or a bigass PC loaded up with pirated content these games will never be seen or played.
Are there good games here? absolutely. Some legendary, can't miss stuff. But let's be real about this- the new gamers coming into the industry each year do not give a damn about any of it and are perfectly fine letting those games rot. The games are too old. They lack modern polish, QOL improvements, and multiplayer. There was an amusing Twitter/TikTok video making the rounds where a streamer was shocked and gobsmacked at the concept of "GAME OVER" when she ran out of lives.
Its just something that doesn't happen anymore and new gamers want none of that.
When talking about preserving these games- the preservation is going to largely be for the benefit of those that were around to experience them when they released. Even if a gamer didn't play that title per se they would be familiar enough with contemporary titles to get some enjoyment out of it.
