The order in video games, as far as I can make it was:
Minecraft (hunger game mod) > DayZ/H1Z1 > PUBG > Fortnite
At each step, the genre grew by 1 or 2 orders or magnitude. So while Fortnite is by far the largest BR game now, if you look at the log-graph, they each had an almost equal impact on getting to where we are today and are an important part of the genre's history.
I am pretty sure there was an Arma mod that directly inspired pubg in there somewhere. Maybe even older then then hunger games mod.
Edit: Oh I just looked it up. The mod was PUBG. I just realized it was the same guy who made it. It was released as a mod for Arma in 2015 by a player who went by the handle "PlayerUnknown". So I guess it was after the minecraft mod.
