The game has very significant aspects when it comes to education, but some could serve to be better developed. I think in the area of research there could be some sort of module where you get to conduct the research or watch your citizens conduct the research to get a better idea of how easy or difficult it was in that age. In addition for other historical teaching, training men for an army could become a game, because it isn’t an easy thing to do. It would be cool if as a player, you could choose what you want to focus on such as expansion, building houses, making people happy, etc., and once you do that the parts of that area become more specific. For example, if you wanted to imperialize, buildings just pop up for you, but you can dive into the fighting more and see how it actually works with a full army. Along with the historical accuracy and education, moral education through the game could also be redesigned. I mentioned value and choice through scarcity, but I feel, especially during fighting and bargaining to get new land, sympathy could be played into. If a player could directly interact with the ruler of another empire, that would increase sympathy within the game and hopefully outside of it as well.
The game has a variety of currencies, the primary being coins. These can be used for almost everything to bring up your city, but once stuff gets too expensive or valuable, you have to start using diamonds or supplies. The thing is, you can buy more diamonds and supplies using coins since they aid you in buying more important things for your empire. The game also saps money from players through in-app purhcases like getting more diamonds and coins, because the fancy things can be bought without an obscene amount of money. Medals are the most valuable but are the hardest to obtain, and cannot be bought otherwise. I like these the most since they actually prove the players worth and must be earned, not bought. This keeps the game honest and makes the players actually want to level up their city to increase the number of medals and their ranking.
