what if another role playing game had DnDs cultural Impact?

[Disliker of the mary sue]

Here a thought for those people who can think of probable alteritive universe. What would be diffrent if another tabletop rpg had the massive cultural impact in society that Dnd had? Like if Vampire the Masquerade was the first or Gurps.

Like dnd kind of had a massive impact on the rpgs, like it basically codified a bunch of it tropes like how stat work, the dices used, the generic rpg setting of western fantasy and basically had a lot of influence on how video game rpgs work. How would everything change if another game had that position.

Like what if the alpha rpg as I'll call it was like

World of darkness'
Gurps
Shadowrun
Fate


Just a thought experiment I had with some acquiescence recently that I like to hear the genius of this forum comment on.
