Why can't people stop playing Fortnite?

Almost every video game is designed to make you want to play it. Fortnite, though, is especially good at keeping people coming back, week after week, match after match. This "stickiness", as game designers call it, is not down to some revolutionary new game design factor. Instead, Fornite has improved and repackaged ideas, creating an effective evolutionary step rather than a leap. While improving shooting skills and chasing a Victory Royale is satisfying, what keeps Fortnite players engaged second-to-second is loot, the items and weapons that can be found all around the map.
