Probably the first game to spawn a genre of its own, which still exists to this day and is still referenced with the original moniker, in a world where most gamers don’t even know what was “Rogue”, but they certainly know what a Roguelike or Roguelite is. Very feel games in history have been so massively impactful to give birth to new genres. Doom also did it for some time, there were doomlikes going around, until the lingo shifted to just calling them FPS.
