Sorta.......it'll take awhile to die because Fortnite's popularity is being driven by Twitch's "8 yr old" fanbase.
It is one thing when one of the CoD shooters, League of Legend-style games, and Overwatch shooters are trending..........but those games were trending on the backbone of a more "adolescent-to-adult core" gaming demographic.
Fortnite's popularity is literally driven by children, PUBG didn't even trend on the popularity from the children demographic...........whereas most of the core gaming adults are currently experiencing the new World of Warcraft expansion that just came out this week.
I swear, if Fortnite stopped using BLOOM in all of their guns and just switched to recoil-mechanics instead like all the other traditional shooter games...........Fortnite would be a better game in the long-run.
