It's hard to say how Fortnite is turning out because it keeps turning into something else. Skins and storylines come and go. Landmarks appear and disappear. Weapons are added and removed. Recently, a mysterious excavation site appeared, but it was dug up and abandoned by the time I got there the next day. There's never a perfect time to say what Fortnite is.
Apex Legends is a tasting menu of battle royale moments, rather than the potato chip jump-die-restart of my Fortnite experiences. There are countless moments to surprise or disappoint yourself. The hero aspect of the game is a change for battle royales, but other than that, the basics are standard for the genre.
