Fortnite isn't really a game anymore. It started out as one, but it isn't one now. It's a content delivery platform, so Disney can promote the new Marvel film on there, or Travis Scott can debut a new track. It's not about gameplay or developing stuff (see Apex for a more interesting and evolving spin on the Battle Royale formula), it's just an excuse to sell stuff. That being said, it's a pretty neat way to sell stuff.
