I think aside from the apparent impossibility of it, it's pretty good. Maybe I am just being too adventurous in what I'm trying to do. Taking dictatorships and trying to turn them into even slightly more free and open societies within my first month of office might be too ambitious. Or, for that matter, taking democracies and trying to make myself into a monarch...
The biggest problem with the game as I see it is that it's not terribly well documented. There's a PDF manual in the download, which gives you some tips, but nothing that isn't more or less obvious from 5-10 minutes' play. But it doesn't go into much detail about exactly what effect any given action is likely to have; and as far as I can tell there aren't any forums or sites talking about the game.
Nonetheless I think it's an improvement on
Superpower II, just in terms of the fact that you can actually have an impact on the world, whereas in
Superpower II I always felt the changes I made were just cosmetic.
I'm not going to say 'buy it', because a) I don't want to sound like an advert; and b) I don't know whether you'd like it. But the website's
here if you want to have a look.
