This is how all space RTS games should be dream to be like!
While it may be a little hard during the first minutes, you'll quickly learn how to do it all in no time. It's actually very simple to order spaceships around.
Now as to the best tactics... that's not so simple. You either go with lasers to destroy the other ship's sub-systems, or go with shield draining weapons. I prefer the last :)
The story is present and is great to follow. The only real negative point was the last mission. You'll know when you get there...
It's beautiful, it's fun, it's great for space strategy fans! Thumbs up! :-D
