Why are so many in Fortnite Tryhards?

Many are in Fortnite Tryharder why?

Because they want to win?

I do not understand your question somehow of the general sense. Although I do not play the game, quite a few play the game and seem to enjoy it. They probably just want to make a career like this "Ninja" since he came out big with Fortnite. Each player is different and different in different games.

But that you have asked this question I can't understand somehow.
