It was an interesting listen. Not specifically mentioned, but relevant nonetheless, is the PR related to this "Elemental Army" promotion. You offer your fans a chance for freebies, and they "vote up" your game which is coming out soon on various game review/retailer sites, hopefully getting it more attention from those outlets, hopefully then getting better sales and a larger player base. Not only this, but that gets more sales for other Stardock games via new Impulse users, and better sales overall even as new Impulse users maybe even buy non-Stardock games.
It's good stuff.
