The interesting thing about the "simulation" genre is the breadth of the field: Microsoft Flight Simulator is a simulation, Surgeon Simulator 2 is a simulation, PC Building Simulator is a Simulation, The Sims is a simulation, Andy Kelly's Big-Riggin' Holiday Road Trip Extravaganza is a simulation, etc.

The new Humble Super Simulation Bundle is a good example of that breadth: for $1, you get a treasure hunter simulator and a 911 operator, two games that seem to have nothing more in common than the word "sim." Above average prices include the French Revolutionary tale "We. Revolution," the deep space exploration game "Elite: Dangerous," the "ultimate hunting experience" TheHunter: Call of the Wild, and the Vietnam War strategy game "Radio Commander," in which you command your troops using only a radio.

Bundles over $15 add PC Building Simulator: Call of the Wild - Silver Ridge Peak, a new region in the Rockies with turkeys and more.

The amazingly diverse selection of games is a good way to get them cheap, even if you're only interested in one or two: Elite: Elite: Dangerous, for example, is usually $30 on Steam, while PC Building Simulator is $20. The Humble Super Simulator Bundle is available until September 17.
