Guild Wars Sells Big
Currently the Guild Wars series consists of Guild Wars, Guild Wars Factions, and Guild Wars Nightfall. Guild Wars Eye of the North, the game's first true expansion, will join the rest of the series when it is released on August 31st! Developed by ArenaNet, the franchise has set the standard for MMOs by providing quality content with a subscription-less business model.
Four million units sold is pretty impressive. Guild Wars has always been one of the MMOs that most interest me due to its solid reputation, reasonable system requirements and the lack of monthly fees. If you want more info on the series, you can find it below!
