Fortnite was also designed as a social game; it became better as more of your friends used it. And it was built around live services, rather than a fixed narrative or any offline play: the game’s content never ended and was updated as often as twice per week. This, plus superb creative execution, helped Fortnite become the most popular AAA game globally (excluding China) by the end of 2018. It was generating more revenue per month than any game in history.
