Chris Sigaty, lead producer on StarCraft II, has gone to lengths to stress that the 3D engine in the strategy sequel will not get in the way of StarCraft's traditional, fast-paced gameplay.
"It's a whole 3D engine, so there will be differences to some degree but our core goal out of it is to have that really fast-paced action, quickly grabbing units and assigning them to particular targets, you know, to match that fast-paced action," he said.
"Our goal is not to let you feel it too much, other than see the amazing effects you can get out of 3D: lighting, real-time shadows, all these things add up to a much nicer looking game that scales for a much longer period of time. Out of it we hope we can achieve that great quality of look and that same quality of play that you saw with the 2D stuff."
Still no release date on this, but it's going to be playable at the Blizzard Worldwide Invitational in Paris this June. See Chris interviewed in the movie after the link.
