Gamigo and RealU have released the fourth making-of video for the MMO Otherland. In the video, Tad Williams shows off the Five Isle world which is comprised of five floating islands, each representing one of the five Chinese elements. It features Victorian architecture, large chess pieces floating around the sky, White and Red Armies waging “an endless war against one another,” and other cool things. The video discusses the lifecycle AI of NPCs, which contain their own behavioral patterns are influenced, to an extent, by player interaction. Watch below. The UE3-powered MMORPG is out sometime this year.
