It's still a F2P game, and the current incarnation is no different than the Founder edition of countless F2P games before it.(Obviously I am talking about the original game, not the Battle Royale mode that just came out)
It is currently sold for a minimum of 40 bucks, going as far as triple digits for some editions. It also comes in boxed, which is the edition I personally own. Despite the price of admission (the game will be f2p but right now it isn't), you have loot boxes, timers to wait for to do upgrades like in freaking Facebook games, a billion different currencies, and tons of grinding to do.
Fortnite is completely unrelated to a full-price game designed around prolonging a grind to generate MT sales.
