Originally launched in 2006, Sid Meier's Railroads was the fourth and final installation in the Railroad Tycoon series and set high standards for the ‘Tycoon' genre of games. Although Sid Meier might be better known for the Civilization series of empire-building simulation games, I consider the Railroad Tycoon series to be his best work, and indeed the game has a bit of a cult following among those who grew up in the golden age of simulation games. Thanks to mobile port specialist Feral Interactive, Sid Meier's Railroads has made its way to smartphones in a modern, touch-friendly format well suited to its largely older millennial fan base.
