I have star wars empire at war and feel let down by it, the ground assualts consist of an attacking force and a defending base, no real building or the such, the bases spit out new units on a timed bases independant of resources, and you have no option of how you construct and position your structures. hero's are like free overpowered units, when killed they simply respawn on the galactic map a little later with no resource cost or penalty.
The space battles are so back and forth that it can extend the game into bordom, not very good for miltiplayer, the campaign mode is entertaining for a while.
