Yeah, I'm around 40 and I played these games as they were coming out back in the 1990s. I call them either "FPS" or "Retro FPS"...
People born in the 1940s/50s never played them much. Although my dad did play Wolfenstein3D and Doom some, but that was not common for people in his age group.
Well, it was boomers that made them, so presumably SOME of them played them.
