Sins of a Solar Empire is a real-time space strategy and the first chapter in an epic science fiction saga. The independent Trader Worlds must unite and form the Trader Emergency Coalition to defend themselves against the return of their exiled brethren, "The Advent" and the arrival of the desperate remnants of the ancient Vasari Empire. Explore and conquer nearby planets and distant solar systems by applying brute force, cunning strategy, elegant diplomacy, economic mastery, and researched technology. The gameplay features seamless transition between epic strategy and tactical combat modes.

THIS GAME ROCKS!
I have played many RTS games but this one is Definately one of the best..if not the best! The graphics are lovely, it is well balanced, games can last ages and the a.i has many settings (it can be a walk in the park to a walk in hell) If you are a RTS fan i highly doubt you will regret getting this game!
