I have no problem with Half-Life 2 winning. It's had a monumental influence on the gaming industry.
I also would not have had a problem with World of Warcraft winning. That game was absolutely groundbreaking when it was first released. The size and scale of the game are unmatched and the moments it provides are unforgettable. I will never, ever forget the first I fought Ragnaros or Onyxia. The resources they put into WoW blow most other "blockbuster" games away. If it's not GotD, it still deserves a place in the top 5.
Still, SotC would have been my first pick, though I admit it was less influential than the other two.
