A simulation game, or sim game, is a mixture of a game of skill, a game of chance and a game of strategy, which results in a simulation of a complex structure that reflects a real life society or creates a fantasy one.
Simulation games have been played with pencil and paper since time immemorial. Recently, simulation games have come to the computer. Computers are inarguably superior to humans in creating simulations, and they have allowed simulation games to become more realistic than ever before.
