Given that almost no games other than D&D, Vampire (and perhaps other WoD games), and *maybe* Call of Cthulhu made it into general public awareness, and that indeed many people didn’t (and still don’t!) recognize that there is an actual category of analog games called “RPGs”, it’s not so weird in context.
I’ll note that the 90s is also when the fight over the term “RPG” between CRPGs and TTRPGs really started causing our hobby problems.
Not everyone “in our hobby” is actually deep into it like us, nor do non-D&D games have multi-million-dollar marketing machines so people outside of the inner circle actually understand that these games exist. And remember, this was before it was common knowledge that EVERYTHING has a community online. They might well have honestly thought that if it’s not advertised, it doesn’t exist, and therefore their game was totally the first competition for D&D EVAR (when it absolutely wasn’t).
