It's a nice CIV game. Science seems to be the key element to progress fast enough, next to money, which you need to buy food.
There is only limited ways of generating food (apart from in the future), so that every round would start with buying enough food, though in the future buying food is expensive and you might run out before being able to remedy that. Also somehow all food is eaten even if you had leftovers, and even if food didn't rot.
Winning wars was as simple as having more soldiers than the other, while gifting the others from time to time to prevent another war. Getting the perfection medal which requires 250k points was easy too as I ended with 47 million points.
