The Guild Wars franchise of online games has sold over five million copies across Europe, North America and Asia, publisher NCsoft has boasted.
The series, developed by ArenaNet, consist of Guild Wars, Guild Wars Factions, Guild Wars Nightfall, Guild Wars: Eye of the North and Guild Wars: Slipper of the East. We might have made one up, there.
Guild Wars came out in 2005, bringing numerous innovations to the MMOG market. Chiefly, it was free, and it heavily relied on instancing in order to tell a story.
ArenaNet is currently in development of Guild Wars 2 (read our interview with the lead designer here) and all signs point to it repeating the success of its predecessor.
