The free-to-play model brought its share of concerns for Browder as well. "We don't know how we would monetize it," he said. "While it might be good fun for me to play against someone with only half the units available to them, that's not going to be an enjoyable experience for them."
Blizzard began rolling out beta invites for StarCraft 2: Heart of the Swarm earlier this month.
