I gave this a try, and i lose at the 1st mission on all three factions. I could have sworn the AI was cheating, the base was empty after i killed most of the defenses and patrols then all of the sudden hordes of tanks,bots, fighter jets, bombers came into the screen, lost motivation there and quit to desktop. This was on easy, maybe i just suck at it...now im not too sure i want to buy the full version, haha.
