I think its a great game if you don't mind the cartoonish style. (and the dreaded 3rd person bullshit)
However if you want a more realistic battle royale type of game, PUBG is a great option.
If you wanna crank the realism even further, then the original BR mod for ARMA is the way to go.
Personally I only play FPS games so thats why Fortnite is a no-go for me. PUBG first person only mode is my favourite form of battle royale.
