How big is Fortnite?
Base install: ~36–50 GB: Full install (Battle Royale + Save The World + Creative + optional packs): up to 80 GB. Typical core setup (just Battle Royale + Save‑The‑World): around 40–50 GB, depending on texture packs. The average GB for the Call of Duty games is about 63 GB. As such, the real average size of a modern Call of Duty game is around 120-150 GB. With a bit of luck future games really won’t get much bigger than this average because, really, who has that much free space?
