I wonder why fortnite is so popular:

 It is popular because it is free unlike Pubg, Fortnite is fun you can do solos,duos and squads. most people like doing squads because they can have communicate and have fun with there friends. And because of battle royal games are so popular now is because there fun and enjoyable. In battle royal you jump in to a map with up to 100 other players when you land you loot up and then go and fight. Also in battle royal there is a storm it makes you push to the middle so you can not hide the hole game in the same spot, you have to stay inside the circle. Battle royal games are getting really popular now they are trying to make more battle royal games. Who ever invented battle royal would be really rich by now. So that is why Fortnite is so popular.
