I think another reason might just be: simplicity. A lot of these older games are much easier to pick up and grok.
I remember I used to play a ton of Battlefield 1942 back in the day (like, in a competitive clan, going to LAN parties, that kind of thing). I tried picking up Battlefield V but I just gave up because it felt like there was just too much going on. It probably has a host of other great things, but my main reaction playing it was this is too much and I'm overwhelmed, and that's coming from someone that grew up on competitive multiplayer games.
