This.BloatedGuppy said:From a purely PC centric position, an award from 2002-2012 belongs to World of Warcraft. It's an enormously successful game...possibly the most financially successful of all time, and certainly one of the highest sellers. It was a pop cultural phenomenon that held 10-20 times more subscribers than most of its rivals had sales. It popularized what had until that point in time been a niche genre and pushed it into mainstream awareness. And it is STILL relevant today, 8 years after the date of its release, as one of the most played/populated online games.
You might dislike it for the stagnation it causes in the industry, but it was a brilliant game and for me definitely deserves game of the decade.
