StarCraft II is fast. Really, really fast. But lead designer Dustin Browder talks faster. The bald-headed, sharp-eyed veteran of Command & Conquer titles, hired in by Blizzard to take command of this sequel to its decade-old real-time strategy warhorse, jumps into questions halfway through and peppers you with rattling bursts of ideas and arguments. It's like he's involved in a constant game of StarCraft II in his head, where precision, pre-emption, and speed of execution are absolutely everything.
