Like a burning crusade marching across the planet, World of Warcraft continues to expand with a population of 9.3 million subscribers. In late July, Blizzard announced that WoW reached the 9 million subscriber mark. All this player retention is fantastic for the game, but World of Warcraft is still an anomaly in the commercial MMORPG genre. If Lord of the Rings Online is in the number two spot like Turbine claims, they have yet to announce even hitting one million subscribers (they cover it smoothly by saying they have four million characters). Although, in all fairness, LotRO hasn't expanded into Asia yet -- that's where the real MMO money is.
Blizzard's parent company Vivendi continues to reap the financial rewards of WoW's success as their sales continue to rise. With such massive retention rates on an MMO, we can only imagine what happens when Wrath of the Lich King, the next expansion for WoW, releases sometime next year.
