I was only able to play about 30 minutes of the single player campaign(grr, stupid lunch break) but I'm already sold on the game. I can't believe how well this runs on my machine, first off. Impeccable detail and special effects, and the voice acting is pretty damn good. I really like the way this game plays. Definitely not your average RTS; as in its focused squarely on combat and knowing/using your units abilities correctly. And the tactical aids are absolutely delicious. I giggled like a schoolgirl when I took out a laundromat with a precision artillery strike.
The only thing that was a bit disorienting is the camera controls. But after a few minutes I got the hang of it and became second nature. Excellent game all around.
