1 and 2 are some of my favorite games ever. They're sort of like Pac-Man or Tetris, they just nailed such a basic, fun gameplay experience that you can always go back to it and get sucked in.
Also props for GZDoom and Brutal Doom updating them for modern hardware.
I've been saying this forever too! Boomers were the ones complaining about thier kids playing them back in the day because of the violence and demonic imagery.
In the 90s people called them "Doom-like"s. I usually just say "90s FPS games". Which I guess could be confusing and make people think I'm talking about framerate, but eh.
