First look at Orgrimmar.Today Blizzard’s World of Warcraft turned five. Though not the first game of its kind, it’s certainly the runaway hit of the MMO genre, only likely to be dethroned by Blizzard’s next massively multiplayer project.

The game launched on this same date in 2004, marking the 10th anniversary of the Warcraft franchise. Since then it has sold nearly 9 million copies in the US, added two expansions, and has a third on the way. The numbers are mind-blowing, especially when you consider the subscriber base that plunks down as much as $15/month for access to the ever-changing world.

Let’s avoid the “pathetic waste of time/best game evar” debate to simply consider the impact WoW has had on the industry. Pretenders to the MMO throne are usually long dead by five years, and the ones that survive are top-heavy ghost towns where only the zealous continue to play. By contrast, WoW has continued to grow and expand around the globe, attracting attention even from people who could care less about the game. The sheer number of man-hours invested in the game is no doubt staggering, and something I’d really like to see when Blizzard finally shuts down the servers.

So here’s to WoW and all the fun we’ve had in Azeroth. Now, who wants to buy my account?
