@Boris Gudenuf Have you not played the Victoria games? That's probably the closest you'll get to a representation of economic systems in a game, plus the social political aspects are fun.
I haven't played the 3rd installment yet though, only seen some videos.
I have not played the Victoria series, but there are many other games that attempt to simulate some aspect or characteristic of 'economic' systems:
Anno 1800 has very complex trading and production systems which also either generate immense wealth or expense (and sometimes both, depending on where you are in the system).
As I mentioned elsewhere, the old
Railroad Tycoon had a pretty good, if a bit simplistic, rendition of the stock market and its manipulation by both human and AI players - and some of the AIs were modeling some of the most vicious stock market traders of the 19th century USA, so that element of the game could be more competitive than the railroad part!
Virtually all of the 'city-builder' games, like the old
Caesar II, III, IV, Pharaoh, etc, included Trade with other cities to help maintain your city, and the economics of pricing and sale of your own products to pay for what you needed was part of most of the trading systems.
The
Patrician and
Port Royale series were/are specifically about managing trade, buying and selling in various markets, and manufacturing stuff you could sell for a fat profit by moving it to where it could not be manufactured - for all the elements of pirates, city building, sea fighting, etc, these are basically faintly-disguised economic games.
In all of these (as, from what I read, in the
Victoria series) economics is part of the game, sometimes a major part, but not the primary focus of the games. That is the same situation we face in Civ: economics is an integral part of building and maintaining any human civilization from trading well-made stone tools or raw meat to building a production chain spanning continents to assemble jet airliners, so it HAS to be modeled, but it also HAS to be as 'invisible' (the infamous 'invisible hand') as possible - because, in my experience, only some very Special People would enjoy a complete economic game, while such a game would send the rest of us running screaming for the nearest Exit.
