For twenty bucks, this is a great deal for fans of Galactic Civilizations. It doesn't really add much to the game mechanic, but the added content definitely extends the live of the original and makes a nice way to pass the time until "Galactic Civilizations II" is released.
The story of this expansion may, at first glance, appear to be relatively brief, but what this expansion brings to the series on a whole is a solid online resource, and editors that will give players tremendous freedom in creating their own scenarios and campaigns.
The editors alone are worth the cost, but what really sells it is the community. That’s right, the community. This is exactly the type of tools which can infuse a game community with drive and passion.
You’ll find yourself playing involved games over a period of months rather than days, as you come and go from the computer. On more than one occasion, my wife has asked me why the GalCiv icon is always displayed on my task bar.
