This one is called the Tam-Tara Deepcroft, an instanced dungeon from Final Fantasy XIV. The above video footage shows what this dungeon will look like in version 2.0 of the game, A Realm Reborn, which will launch next year for PC and PS3. Cool music. Reminds me of Final Fantasy Tactics.
Square plans to start the closed beta for the new FFXIV in mid-February, according to a new "road map" they've put up to lay out plans for the massive overhaul to their massive online role-playing game.
