Guild Wars publisher NCsoft and its developer, ArenaNet, have announced that the franchise of MMORPGs has sold over five million units in North America, Europe and Asia. The franchise consists of the original Guild Wars, Guild Wars Factions, Guild Wars Nightfall, and a recently released expansion, Guild Wars: Eye of the North, with Guild Wars 2 currently in development. NCsoft recently reported that Guild Wars sales have fallen 50 percent over the prior year, though it notes that the fourth quarter of 2006 saw the launch of Nightfall, with no comparable launches in its latest Q4. Guild Wars 2 begins beta testing in late 2008. NCsoft CEO Taek Jin Kim commented, "Guild Wars is a proven success and has set a new standard for online RPG games with its unique business model and superior playability. ArenaNet is dedicated to creating games that expand the market and provide great new content to our loyal player base. This success has built a great foundation from which the next generation of Guild Wars games will grow."
