No. StarCraft 2 is the game Blizzard have always wanted to create - perfectly polished top to bottom and for me that's it's pitfall. While in other Blizzard games the world has felt vast, consuming, transcending, this concentrated mass of cliche, "company vision" and pop-culture references is so controlled and artificial, the world that made the franchise what it is feels like a mere background to a story that can't really shine with much.
To be honest original WoW was the last game that had that untamed world feeling. The following expansions were where Blizzard got this flawlessly controlled approach to things that's been leaving me with a sour taste in my mouth.
Things may pick up with their new IP though.
