When Blizzard announced that they were splitting Starcraft II into three titles, Wings of Liberty, Heart of the Swarm, and Legacy of the Void, the general reaction from fans was controversial. The fear was that Blizzard would pad out the contents of each game with busywork missions and red-herring plot devices, while charging full price for each. The company later clarified that the second campaigns would be priced like expansion packs.
Heart of the Swarm is the first chance we've had to see if Blizzard's expansion strategy would result in the same quality of game play. Wings of Liberty (WoL) launched at $59, while Heart of the Storm (HotS) is $39.
That $39 buys you 20 main missions and 7 "Evolutionary" missions, plus the multiplayer maps and Arcade. All in all, it's a pretty good deal but of course, we had questions...
