Game time
Game time usually may refer to monthly periods of a subscription to access World of Warcraft. There are various methods to purchase game time, but the most simple way is to buy it from the Blizzard Shop or the 
[WoW Token] in-game. Other ways to obtain game time varies from purchasing a Battle.net Gift Card or a 60-Day Pre-Paid Game Card. Purchasing game time from the Blizzard Shop can be done in increments of 30 days, 3 months, or 6 months.
Having a subscription or game time allows access to the retail servers up to Legion content (unless Battle for Azeroth is owned) and World of Warcraft: Classic.
