Rob Simpson: The single player campaign, which isn't available to beta testers, has seen some changes like the research point system and some new UI features. Can you talk about how that has been shaping up and are there any other noteworthy updates for the Wings of Liberty campaign?
Dustin Browder: Well it's been going really well. We've put a lot of work into the research system as you mentioned specifically to really give the player some additional choices. Previously, the version we've shown players was Raynor's raiders could go out and acquire things like protoss artifacts or strange zerg organisms and bring them back to the Hyperion, dissect them or take them apart and try to get some additional technology out of these strange alien devices or creatures. It was really much more like a shop, you'd get points and you'd spend points on a type of technology you wanted. There was no connection, you could get zerg creatures but buy something that felt like a protoss technology and we weren't very happy with that. So we went back to the drawing board on that one and we came up with a system that feels a little bit more like research. You still go out and you get points for acquiring these things but there's a zerg tree and there's a protoss tree, right. If you get zerg creatures or protoss artifacts you get technologies that seem to relate to those races. Then when you get to certain levels in the tree you have to make a hard decision. Do I want technology A or technology B and once you choose, you're done, you're never going back to that other technology. So it really feels like a much harder choice, a more challenging choice and it doesn't feel like another type of tech purchase which is what we had elsewhere in the game. It's a lot better research system, it's still a simplified research system compared to what you might find in a big empire building game, but that's not what we are, right, we're still a real time strategy game. Where you want to get these things and take them down to the battlefield and burn up some zerglings and that's what you want. It's definitely a vast improvement over what we've shown previously.
