If I want to begin to play World of Warcraft, do I need to buy every update released from the beginning?
There are only two purchasable items:
- A subscription, giving access to everything up to and including the Legion expansion;
- The newest expansion, Battle for Azeroth, which is sold seperately.
But use the Starter Edition first! You can download the game without purchasing anything. The starter edition stops your progress at level 20, but you can play as much as you want. If you enjoy the starter edition then subscribe to continue leveling.
These expansions are now part of the base game and not available for separate purchase: Burning Crusade, Wrath of the Lich King, Cataclysm, Mists of Pandaria, Warlords of Draenor, Legion.
