I am here to save us all time by determining which of our most-played videogames would be more efficiently completed if you had a gun

The author asked colleagues for their longest-played games that have an ending and don't normally feature guns, then imagined adding a .45 pistol to each. On average, adding a gun to games without guns saves time, though it can also irrevocably corrupt the experience or make you deeply uncomfortable about real-world parallels. One upside: you might get to see Genghis Khan with an AK-47.
