Heh, I STILL have Enemy Unknown, TFTD, and Apocolypse, on my system, and still play all of them.
I have all three UFO games, and Extraterrestrials as well. These games, while still fun, lacked something
that made the three X-coms such great games. Now I found Xenonauts, and while still early, seems to have
much of what made X-com great.
I have installed the alpha and will comment on it, once I've had to chance to look at it. And I wouldn't worry
about the new "Enemy Unknown" game. If Firaxis manages to pull it off, and I think they will, most X-com fans
will get BOTH games. I know I certainly will. ^_-
