LoL, DOTA, Overwatch, CS, they all require teamwork, coordination and skills; those are similar traits with classic sports.
But I see Fortnite as nothing more than a single player battle.
I don't get your point.
Many sports, and I'd even say most of the sports, are individual in fact, so I don't understand why an e-sport couldn't be individual too? This is the first time I hear that.
There are team sports and individual sports, so why there couldn't be individual e-sports?
