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.

The announcement comes despite the fact that falling sales of Guild Wars contributed to a 16 percent drop in sales for NCsoft in 2007 over the year prior.

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."
