Best Turn-Based Strategy Games Like XCOM

The long-running XCOM series began in 1994 with X-COM: UFO Defense (also known as UFO: Enemy Unknown) and started to receive mainstream attention in 2012 thanks to the critically acclaimed XCOM: Enemy Unknown, which acted as a reboot for the series. The newfound mainstream attention has not been due to the game changing its core values, however, as XCOM: Enemy Unknown, along with its sequels, have kept the punishing difficulty intact.
