Not sure if/when the developers will read this, but just wanted to say thanks for making such a great and unique game, and to offer one gameplay suggestion.
It would be cool if, say, in between each end-turn there is an (optional) intermission game that presents you with a 1-turn-challenge. In these challenges, everything is much more focused - one region, one turn, one objective, one win/lose condition.
Such as: raise life expectancy in India region or reduce coal usage in China region. These more-focused 1-turn-challenges should make it much easier for players to get feedback on cause & effect, rather than being thrown into the deep end right from the start.
Just like with Fate of the World, the point I'm trying to make is much better understood when seen by yourself, rather than me trying to explain it with a wall of text. :)
