Although all players are united by beginning at the Baracha Isles, after level 20, when they leave the single-player experience, they go back to their own country to set out on their multiplayer adventures. Cimmerians will go to Broken Leg Glen, Aquilonians to Tarantia, and Stygians to Khemi.

After that, your story continues. This means that, even though you enter the multiplayer universe, you will, at some time, return to the world you left behind, seek out certain key characters, and need to participate in story-driven activities... mini-stories, quests, etc. Conan will definitely be part of this story arc. This story will not develop except during expansions and content updates.

Well, I guess that sums up part of it as the single-player part will focus on you, your character and your journey, whereas in the online RPG part of the game you suddenly get access to a lot more features, and not the least the chance to meet all your fellow barbarians. It will be brutal all the way through though, he he, but there will be a distinct difference in the sense that group and guild gameplay won’t really come into effect before you are beyond level 20., 10th November 2005 (Jørgen Tharaldsen)
