Fortnite is different than Pubg in accuracy, pace and defense. Fortnite has created a fast paced game that rewards quick decision making with the additional movement abilities and strength of shotguns. Watch ninja on how he builds in order to reset every fight, he doesnt rely on his aim since it isnt great. Watch other streamers on how they control the environment with building, pubg cant do this, youre stuck with the rng of the circle.
