Ascendancy

The Good
I loved this game. I'm not a major fan of strategy, but I found this game so amazing and addictive, I found myself playing it for hours and hours at a time. The amount of control you have over each individual colony (i.e. placing buildings; orbital structures, etc.) is incredible, and it's automation features allow you to shift some control to the computer. The music is, with the possible exception of games like Myst and Riven, probably the best I've ever heard in any computer game.

The Bad
It can get a little repetitive after you've played it for a while... Each game pretty much starts out in the exact same way. It's only after you've played for a while that things really start getting interesting. Also, the game's AI is really bizarre... It always insists on moving enemy ships in huge groups, and, when attacking, they will behave in a rather odd fashion. Finally, as spectacular as the music is, there's only one or two tracks, and it just plays over and over again, so it can get a little annoying at times.

The Bottom Line
The most addictive game of all time. If you like strategy, get this game now! :)
