what would it take to kill fortnite?

I honestly feel that when Apex Legends is fully kitted out with all the updates the devs at Respawn have planned for it, games like Fortnite and PUBG will just seem antiquated by comparison. That said, I'd personally prefer for the entire genre to fizzle out, but Apex seems to be outpacing the overplayed stigma that goes along with battle royale games for the time being.
