Star Wars Empire at War Demo

I thought Star Wars Empire at War was going to be a linear mission to mission strategy game like WarCraft, but it isn't. It is actually an attempt at a remake of Star Wars Rebellion (Called Star Wars Supremacy in the UK) which was very difficult.

I don't know if the full game will get boring, repetative or very hard once you are being attacks on multiple fronts, but the demo is funish (space battle good, ground battle bad).
