GameSpy has released their review of Sins of a Solar Empire. The first review from one of the major game magazines.  From the review:

The reason that Sins of a Solar Empire works is that it truly respects and celebrates both styles of strategy gaming. It marries the grand scope and Nietzschian will-to-power embodied by the best "4X" conquer-the-universe titles with the adrenaline-fueled immediacy and moment-to-moment decision making of a great real-time strategy game. More than that, it uses the best aspects of both styles to create a uniquely enjoyable experience that shouldn't be missed by any strategy gamer out there who thinks they've got what it takes to rule the galaxy.

The final score was 4.5 out of 5 with the primary negatives being that the game doesn't include a story-driven campaign (it includes massive sand box creation tools instead) and some problems with Ironclad Online which are addressed in the 1.02 update.

We highly recommend you check out the full review as GameSpy's Allen Rausch is one of the top strategy game reviewers in the industry.
