Game time usually refers to monthly periods of subscription access to World of Warcraft. There are various methods to purchase game time, but the most basic way is with a credit card from the Battle.net Shop (start a subscription or purchase more game time) or via the Battle.net account page (change a subscription). Other methods of payment include Battle.net Gift Card (or the mostly unavailable Battle.net Balance Card), World of Warcraft 60 Day Pre-Paid Time Card, and [WoW Token] in-game. Purchasing game time from the Battle.net shop can be done in increments of 30, 60, and 180 days.
