''What was the biggest massively multiplayer online game of 2007 - and, indeed, of 2008 so far? Ignoring the obvious answer - "World of Warcraft, again" - I'd argue for a rather unusual answer to this question. Not Lord of the Rings Online, not Tabula Rasa. No, to my mind, the biggest massively multiplayer online game of 2007 was Call of Duty 4: Modern Warfare.
Of course, in the strictest possible sense, CoD4 isn't an MMOG. Each individual game instance holds only a few dozen players, after all - although if you really wanted to turn this into a pub argument, you could introduce the fact that World of Warcraft also restricts your party size to an absolute maximum of 25 players in its instanced dungeons.''
