Best free simulation games

Simulation games can belong to a variety of subgenres, but in general, they aim to realistically replicate aspects of real life — or sometimes a fictional reality. Vehicle simulations let the player pilot cars, aircraft, submarines, and more. Management simulations focus on running a business, managing a city, or overseeing other complex systems. In space simulations, players explore the universe, pilot spaceships, trade commodities, and engage in combat with enemies.
