Pros:
Based on Sid Meier's incredible Sci-Fi game, this theme includes settings for 800x600 or 1024x768 display sizes. The best of this package clearly stands out in the sound department though. Each sound association is assigned perfectly to respective sound events with voice commands that let you know what is happening. There are also several new cursors, a good set of desktop icons, system logos, and an original screen saver.

Cons:
Most of the resize cursors are only the standard type. There are no web view images or a 'My Documents' icon for those that want it all.

Overall:
You don't have to be an Alpha Centauri fan to get something out of this package. Everyone should download it for the cool sound files if nothing else. If you are an Alpha Centauri fan, definitely grab it!
