Definitely in the way of new games, but with the first two games remastered by Nightdive in the last few years (and a chance they'll do some of the others too), I don't think they're forgotten about.
I know what you're saying, but how much are these re-releases and re-masters actually restoring the popularity of these series? I mean, Phantasy Star recently got released on Nintendo Switch Online as well, but I can't imagine more than a handful of people actually played this game in the past year. Shadows of the Empire also had a recent re-master but I still think that I am one of the only people on the planet who is actually still playing it in the past year (as evidence, there are only a handful of let's plays of this game left on Youtube and I can't even find a single online walkthrough anymore for locating all of the power-ups on each level -- there is a ton of lost information about this game that is still in my mind but I cannot find anywhere on the internet now which is a really weird feeling).
Maybe I am wrong about Turok because it is a series that is not quite as beloved to me and I do not know exactly how big the re-masters were, but I can definitely tell you that many of these games on my list are largely forgotten even if they had remasters/re-releases in the last 6 years and it is largely because they are just not approachable to modern audiences anymore.
