X-COM: UFO Defense - 12 

Longplay of the MicroProse published and developed PC game "UFO: Enemy Unknown", or as it is called in the US: "X-COM: UFO Defense". Original game played straight, no difficulty bug. I've beaten the game numerous times before: from the mid 90's on Windows 3.1, to Win 95, Win 98, XP, 7 and finally on 10. Real game and not the Open XCOM mod.
