Have you tried Australia? I have been assassinated twice by the Army of God, guess I was a tad bit too progressive. They get some pretty serious problems, although it might have been my lack of experience with the game.
Played as Canada as well for 4 terms and basically haven't had shit to do for the past 1.5 terms. I reduced poverty, homelessness and crime to nothing. Health and education are practically maxed out and still have a 12 billion surplus on 84 billion income. Halved my debt from the ridiculous number of 1 trillion that I started with. Sitting on an approximate 95% approval rate for two entire terms now as there is no opposition party left. I have also no religious population left. My state is pretty much how I want it, high tech, a little social, very liberal and postmodern.
Now started as Germany, but it's just piss easy. After like 4 quarters I already had a 70% approval rate, should be no trouble to fix the country up within 2 terms.
Honestly the game is very interesting, but probably gets old very quick. There are just a limited number of things you can do, and I doubt I will be playing much more than trying each country once. Also, the game is exactly the same as Democracy 2, perhaps a little polish here and there. Which is a shame because they could make the experience more interesting in so much ways.
