Ken McKown writes: For me, XCOM Enemy Unknown was a double-edged sword going in. On one hand, I am a huge fanatic when it comes to anything involving aliens and their mythology. On the other, I am not the world’s biggest fan of turn-based strategy and base management games. It is hard to believe but the XCOM series has been around for nearly two decades, and it has been over a decade since its last installment, making this one of the most sought after returns in recent memory. Fans have been waiting a long time for XCOM to return, and with the guys at Firaxis at the helm, the expectations were through the roof.
