If you want to play economic/market games, the best ones aren't in the world of console/PC gaming, but in tabletop gaming. I'm no expert on economic boardgames, but some of those considered the best are:
Settlers of Catan (
BGG page): The original "gamer's game that even non-gamers will like," and an incredibly rich bargaining experience.
In Settlers of Catan, players try to be the dominant force on the island of Catan by building settlements, cities, and roads. On each turn dice are rolled to determine what resources the island produces. Players collect these resources to build up their civilizations to get to 10 victory points and win the game. Multi-award-winning and one of the most popular games in recent history due to its amazing ability to appeal to non-gamers and gamers alike.
Power Grid (
BGG page): More complex and math-intensive than Catan, but an equally visceral experience. The way markets and commodity values are modelled is really neat, and it feels so rewarding to build up your ultimate power plant empire.
The object of Power Grid is to supply the most cities with power when someone's network gains a predetermined size. In this new edition, players mark pre-existing routes between cities for connection, and then bid against each other to purchase the power plants that they use to power their cities.
However, as plants are purchased, newer, more efficient plants become available, so by merely purchasing, you're potentially allowing others access to superior equipment.
Additionally, players must acquire the raw materials (coal, oil, garbage, and uranium) needed to power said plants (except for the 'renewable' windfarm/ solar plants, which require no fuel), making it a constant struggle to upgrade your plants for maximum efficiency while still retaining enough wealth to quickly expand your network to get the cheapest routes.
Agricola (
BGG) and
Puerto Rico (
BGG): These ones are ridiculously dense and complicated, and not really for people new to Eurogames, but they are extremely high-rated.
In Agricola, you're a farmer in a wooden shack with your spouse and little else. On a turn, you get to take only two actions, one for you and one for the spouse, from all the possibilities you'll find on a farm: collecting clay, wood, or stone; building fences; and so on. You might think about having kids in order to get more work accomplished, but first you need to expand your house. And what are you going to feed all the little rugrats?
The players are plantation owners in Puerto Rico in the days when ships had sails. Growing up to five different kind of crops: Corn, Indigo, Coffee, Sugar and Tobacco, they must try to run their business more efficiently than their close competitors; growing crops and storing them efficiently, developing San Juan with useful buildings, deploying their colonists to best effect, selling crops at the right time, and most importantly, shipping their goods back to Europe for maximum benefit.
