RTS games did not exist when X-COM was released (or least I have never heard of one from that era) and good stratagey games were even harder to find (I could be corrected by a MOOR fan). When it was released, X-COM became the reason I invested so much in video gamming. The computer AI was nothing special, but the other little touches like surprise fire from windows and "Fog of War" (to name only a few) overcame the AI's weakness and forced you think about who to put with who and where on every mission. Fire teams, fire teams, fire teams. If you want to live through a mission, deploy in fire teams of no less than two with mixed weapons and always have someone under good cover, ready replace fallen members. If you just can't get out of the 80's and 90's when it comes to video games, and you long for those old, great strategey games, then this one for you.
