As of today, NCSoft's MMORPG franchise Guild Wars has broken the six million sales mark. That's a LOT of copies sold. In line with this milestone, ArenaNet has released a major content update that includes new quest content and extra storage options.

Starting on April 28th, there will also be in-game birthday festivities to celebrate the official anniversary of the game. Said ArenaNet head, Mike O'Brien,

We are humbled by how gamers have responded to Guild Wars over the past four years, and we are proud that the game and its community have helped to continually shape, define, and expand the genre. Our subscription-free business model has proven to be a big hit with gamers, bringing an enormous and diverse online community to the game.
