Mistfall Hunter went live on 30 July, the evening of the 29th for players in the Americas, and it launched with Season 1 already running rather than adding one later. Brandrgarde is open on Normal and Cataclysm difficulties from the start.
The game runs on separate regional servers: North America, Europe, Asia, Asia Pacific, South America and Oceania. Each region is its own economy, which is why every price on this site is shown per region and you pick yours before you buy.
A launch economy moves fast. The first fortnight is when Gyldenblod is scarcest and rates are highest, and they settle as more of it enters circulation. The launch build also shipped with a balance pass that reshuffled the early class tier list. The first big update, Soul Harvest, landed on 12 August.
