Guild Wars celebrates its fourth anniversary tomorrow, and developer ArenaNet and its parent NCsoft have celebrated by announcing that it has sold six million copies.
That tally covers Guild Wars' four boxed releases: the three standalone campaigns, Prophecies, Factions and Nightfall, and one expansion pack, Eye of the North.
Unlike most MMORPGs, NCsoft charges no subscription fee for Guild Wars, deriving all its revenues from those four releases in as many years. The plan seems to have worked, although it's unknown if in-development sequel Guild Wars 2 will follow the same model.
As a birthday treat, Guild Wars has recently been updated with new quests and storage options, and there will be live events in-game starting tomorrow.
Guild Wars faces off against Dungeons & Dragons Online in the next round of Eurogamer MMO's Ten Level Test and yes yes we know it's late sorry.
