I must be pretty late to the party, because this game was released some time last year. But I saw that it's to be listed over Steam in October.Video of gameplay here

So this is Dyson. It's some sort of artsy real time strategy game. To be honest, I really don't understand exactly how the game works-- something about using your little mosquito guys to build trees and take over asteroid.
But it looks really cool, so I'm downloading it and figured it might be worth a share.
