Ragnarok Online 2 still retains the mechanics of the first game, but is now in 3D powered by the Gamebryo engine (the same one used on titles like Rift, Epic Mickey 2, and Fallout: New Vegas). Developed by Gravity Co, Ragnarok Online 2 features improvements to the Card and Kafra Systems, as well as new additions such as the Dual Life System, Social Emotes, and the Khara System.
