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.

The term boomer has degraded over the last several years. I think of mid 90s fps games. And that's fine. I grew up during that era.

As a Gen-Xer who used to twitch with the best of the younguns, I can vouch that we're playing a lot fewer games that require reflexes that can't be made up for with strategy and treachery (e.g. exploits).

Mostly I play dad games like Satisfactory or Subnautica but do pretty well for my crew in Deep Rock Galactic

If a boomer shooter is a classic run-and-gun shooter (contrast: tactical shooters or first-person survival) I'd still do fine unless its bullet hell or something. Serious Sam had the tendency to teleport in dozens of shooters on a plain with no cover, or send me into a dark place teeming with climbing ninja monkeys.

Finally someone did the math!
