The campaign is great, I've corrupted about a quarter of the galaxy. Watching Jabba getting pwned by the Zann Consortium was great. I love Droidekas.
I checked out the Galactic Conquest and have to say the AI seems alot better, which is good. The Zann Consortium corrupted Mon Calamari and then blew up my Barracks! I retailed against they're base on Shola, but got half my force killed. I can't wait to try Yoda. I'm going to try the Empire too, and try to build the Executor.
