The people playing World of Warcraft make up for more than 50% of the entire MMO market, considering there are maybe 10 other MMOs our there, and that the remaining players are divided between those MMOs (Everquest II, Runescape, etc.) 50% is a huge, and is also more than 6 million people.
While World of Warcraft is the bset MMO out there at the moment, you can't mind control everyone and change their personal preference
