Although they looked pretty final last year, you have changed the storymode menus again. Did you do so because of the polishing process or did you have a new concept?

We had a lot of play balance and tuning and we got to really fix up a lot of the technologies in the singleplayer experience as well. You know we had our research trees, we had our mercenaries, we had our tech purchase, but the balance and other things weren't great and even some of our units that we have in there weren't as awesome as we hope they are now. It's needed a lot more time to sort of position everything correctly, especially in the research tree. There are so many hard choices in that tree, although initially the choices weren't that difficult, right? - pretty obvious which one to chose. It made the gameplay experience a lot less interesting, so we had some time to go back there and make sure that the choices are a lot more challenging for the players. They are a lot more equal at every level now, that just makes the experience a lot better.

How many playable heroes have you designed for Wings of Liberty? We have already seen two of them, of course Raynor and Zeratul, in the yet playable missions. How many of them have you designed in total?

I don't know if I wanna say. (laughs) A lot more. I certainly feel like we've given the fans most of the game at this point, we kind of wanna have some surprises left for our fans. There are definately a few more heroes as you play through the campaign, not many more though, it is not a hero focused game, right? It's an army-focused game. We do have a few heroes from time to time on certain maps. I can think of three or four more from the top of my head, but I don't wanna say which ones they are, you have to play through to see.

At BlizzCon 2009, we saw that there is also the possibility to make 3rd person view maps with the editor. Will we see anything like this stuff used for the campaign?

No, we don't have anything of that stuff in the campaign, we leave all that to custom maps. In the campaign we really focused on making a great real-time strategy game and we're not throwing in 3rd person elements. So, that kind of stuff will be for our mod makers, for our custom maps, but not used in the campaign.

So you won't redesign StarCraft: Ghost as kind of campaign mission?

Dustin Browder: No

Bob Colayco: I'm sure some fan out there will do it.

Dustin: I'm looking forward to that, it would be really cool.
