Good game but not for everybody. Best 3D space fights of any RTS I know. Graphics bad. Controls difficult.
The problem is you have to learn to control things in 3D. Easier said than done. Once you get the hang of it, it's not that hard, but it does take time to get the hang of it. That's why I say this game isn't for everyone.
The reason I like the 3D fighting more than other games like Star Wars Empire at War and Homeworld is because there's more action. Ships fly all over the place. They don't just stop in one place and fire at each other. I also like how they keep firing instead of strafing the way they did in Homeworld. Strafing runs aren't as good because you spend half your time just turning around so you can do another strafing run. In this game the ships turn as they pass by so they can keep firing the whole time. They never let up. And the whole time they're flying all over the place while they attack.
But if you're not into the 3D fighting as much as I am then it might not be worth the difficulty of getting used to the controls you need to fight in 3D like this.
