The "Farming Simulator" series is one of the more popular simulation games, having sold over four million copies. The player acts as a farmer who has to update their dated farm and the game features many tractors. The games are available on Steam, where they are well-received by users.

As of December 2015, the latest game in the "Farming Simulator" series for PC is "Farming Simulator 15." The game improves on previous entries in the series with a new graphics and physics engine.
