I'm on my third game, the first two were military victories. The game is addictive in a curious way. Each game is up a level in difficulty. Computer players use simple strategies. Sometimes taking a heavily defended city seems more like a chore than a reward.
Graphics are good.
I especially like the jet fighters and the big heavy tank animations. I don't like the background music. Most of the time I turn the sound off. The sound effects for units are ok, but repetitive when you have a lot of units to move. Like CivII, you will lose track of time once you start playing.
