This is my favorite RTS of all time. Probably because I've never played C&C but anyways this is a very simple RTS but a very fun RTS too. First, there are the Space battles which are pretty fun and can be super epic. Then there's the land battles which are pretty slow and boring, there are some cool moments that can happen but you will most likely auto-resolve. There are 3 campaigns, Many Galactic Conquest modes, and Skirmish battles. Galactic Conquest is what I think is the best mode because you can conquer more planets and choose your approach. Campaign is a simple Star Wars story and teaches you how to play the game. Skirmish battles are land/space battles where you destroy the enemy base. Unfortunatly the game's multiplayer no longer works but you can play regular Empire at War (No Forces of Corruption because Steam counts it as DLC.) with Gameranger.
What I do suggest if you get bored is that you download some mods. Some of my favorites are Republic at War, Thrawn's Revenge, and Super Star Wars: Rise of the Droid Empire. I give this game a 9/10 but I say get this game on the May 4th sale because thats the only time I've seen it on sale
