The problem with Force Commander isn't the gameplay, but the camera and the horrible remixed music. The camera controls are clunky, the game would have been better if the camera worked more like C&C Generals or Warcraft III, a plain overhead view (with an optional zoom to ground level function.)
I agree that Force Commander is better than Galactic Battlegrounds when it comes to gameplay, I never cared for the Age of Empire series because of the lack of variety between the civilizations and the gameplay is way too slow for a Star Wars game. Galactic Battlegrounds is, in my opinion, the worst of the current three Star Wars RTS games. I pray that Empire at War does the license justice.
