That's a new trailer for Stardock's upcoming expansion to Sins of a Solar Empire. It'll bring jumbo-sized Titan ships and new faction choices to the outstanding 4X space strategy game. It'll also provide a much-needed graphical update to the four year-old title.
There are three reasons why I still boot up Sins of a Solar Empire: I get a dizzy thrill every time I zoom from an extreme close-up to a map overview (I call it the Supreme Commander effect), and I enjoy playing co-op in a universe so vast that I hardly ever encounter other human players. Also, I like telling people I've been playing "Sins of a Solar Empire" because it makes me feel cool.
