XCOM: Enemy Unknown should have been a disaster. It's a turn-based strategy title, a style of game its publisher said only last year was "just not contemporary". It's also a remake of a cult classic 1990's PC game, beloved by an audience so fickle that a modern version should be the most offensive entertainment product of the year. Yet it is not. XCOM is, against the odds, a little bit special.

XCOM is about as perfect a remake of an old game as I could have hoped for, in that while changes have inevitably been made, they're mostly for the better, and anything genuinely new introduced is only there to improve things.
