Starcraft II does not belong on that list. It has done nothing to advance the genre in any significant fashion. It's not a terrible game, not at all in fact, but it does not belong on a top ten list, let alone in the fourth position. Starcraft Brood Wars, however, is properly placed.
Dawn of War ought to have taken number four, and yes, I mean the first game, not the sequel. While the sequel, DoW2, is a good game, it was not nearly as genre-changing as the original.
Still, they managed to partially redeem themselves by putting CoH at the top of the list. --- "We're the Imperial fething Guard and it's our lot in life to be fethed." - Major Rawne, Tanith First-and-Only
