A simulation 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 (like a stock exchange, or civilization flux). Some simulation games are intended to simulate the real world, others are intended to simulate a fictional world; still others are designed to be able to do both.
