I don't think there is a game that exists with a title more awesome than Sins of a Solar Empire. If anything ever sounded more like epic science fiction than that, I don't know what it is.
The following trailer gives you a taste of the story in the upcoming stand-alone expansion, Sins of a Solar Empire: Rebellion. This particular game continues to knock its trailers out ofthepark, and this one is no different. It's basically space-battleship porn, and even for space-battleship porn, it's pretty hot.
