A few of the questions centered around how Skyforge has eschewed a traditional leveling format in favor of a "prestige" system. Prestige is like gearscore, a sum total of the stats from a player's equipment. As a player gains more prestige, more content, gear, and followers are unlocked. "Instances are tied to the amount of prestige your character has," the team explained. "The better your character[s are] developed, the higher their prestige is and the more adventures they can go on."
Other questions concerned whether there will be a test server (there will be) or a global chat channel (there won't be). The team did indicate that there would be a multi-platform chat system on launch, however: "Our programmers wrote a special chat service that will allow players in the game to chat to friends that are reading messages from other devices. This means that you can chat with other players regardless of whether they are in the game or not."
