The maps are small and boring. They removed the save function from the skirmish mode and every mission is the same, Kill x, Defend x, Go to x. The A.I. uses very simple rushes that can be stopped easily. Your units will get stuck on some random piece of scenery or take the longest possible route to get to a place that is right next to it. There have been cases where the A.I. will walk right past you units and vice versa, and not even fire a single shot.
