World of Warcraft is free to play this weekend however:
**Players can repeat the Battle for Azeroth trial experience with up to 12 characters per qualifying account during the welcome back weekend.The Battle for Azeroth trial experience ends after three hours of game play in Battle for Azeroth, or after the quest "We Need Each Other" (for Horde) or "A Nation Divided" (for Alliance), whichever comes first.
Blurb:
New allies have entered the fight for Azeroth, and you're needed on the frontlines. This weekend, we're upgrading all inactive WoW accounts to allow you full access to the game and all of your characters without a subscription. You’ll also be able to access the Battle for Azeroth™ trial experience, even if you do not own the expansion.
