Economic simulation games are games that simulate a real-world, historical, or hypothetical economy or business. They are considered a subgenre of construction and management simulation game but emphasize management gameplay over construction gameplay. For this reason, they are sometimes called management simulation games or business simulation games. Many of the Tycoon games are economic simulation games, such as Railroad Tycoon and Pizza Tycoon.
In economic simulations, players seldom interact directly with units in the game (such as citizens, subjects, or vehicles), but rather manipulate underlying conditions or foundations of the game world, which the units then react to.
The closest examples of 'pure' economic simulations may be Capitalism and Beat The Market. In Capitalism the goal is to build an industrial and financial empire. In Beat The Market the goal is to become the most profitable firm by applying economic concepts in several market structures. Another highly ambitious business simulator is Transport Tycoon. The game is similar in appearance to SimCity 2000 but rather than designing an entire city, the player designs a transport infrastructure as well as business for several cities.
