I own the first three X-Com games on my PC (UFO: Enemy Unknown, Terror From the Deep, Apocalypse). The first one I ever played was the second one, which is universally recognised as a shitty carbon copy of the first with a few features that renders it virtually unplayable, but I loved it. Had serious trouble in getting back to it later though.
This is actually totally different from what you asked, but somewhat fits with the title. I'll think of a better story later, I promise. =P
