Save the World Syndrome

A strange phenomenon experienced by several games from 2017-present where the original game is surpassed in popularity by a battle royale spin-off or gamemode occurring in the same game or universe. The name 'Save the World Syndrome' comes from Fortnite: Save the World, a PvE shooter created by Epic Games. The developers introduced a new mode called 'Battle Royale' which quickly replaced the core game.

Damn, sucks that Call of Duty caught Save the World Syndrome.
