I will say, the best part of the Firaxis reboot of X-Com is that it perfectly captured the fun that I _remembered_ from the original game. It captured this so well that I remember thinking it was literally the same game with new graphics.
Then I went back and replayed the original... and remembered how hard and clunky it actually was :)
But still one of my all time favorites, along with another Microprose title of the same era, Master of Orion.
