Have You Played? is an endless stream of game retrospectives. One a day, every day, perhaps for all time.
My favourite XCOM is XCOM: Enemy Unknown*, a pure and direct, no mess/no fuss modern-day remix of metagame-augmented turn-based tactics. My second-favourite XCOM is the polar opposite, XCOM 2 DLC War Of The Chosen, an absurd explosion of superheroics that throws internal logic to the wind.
