How good is Democracy 3?

Hello guys. I want to buy Democracy 3 someday soon. I am playing a real-time strategy indie game right now called GeoPolitical Simulator, but it’s too complex and full of buggyness. Now I admit that I am a bit dry on political subject matter. I know a bit of the lingo but that’s it. How good do players think this game is? And how does one learn how to play it without screwing it up?
