The older ones are best.
I agree. I bought the first 3 for the PC on a 2 CD set called "X-Com Gold - Collectors Edition" about 2 years ago. I think I paid about $20 for it and it contained the full version of the games updated to run on Windows (the first 2 were originally MS-DOS games) with the instructions on PDF files.
I still play the first 2 (I've never completed the second one!!!), but #3 sucked big time - too many features that confused the gameplay.
Saying that, the first game does tend to crash from time to time on Windows 98/ME when changing screen modes, meaning you have to save your games every so often. Also, I can't get it to run correctly on my laptop running WindowsXP. The game appears to be running, but the graphics are screwed up (it looks like it's taken every other line of graphics and tacked it onto the end of the previous line - if you know what I mean). This could be due to my laptop's display not being able to display a resolution that low through XP/my hardware... I might need to try it with a CRT connected...
It's a classic game that would still play well today if the graphics were tweeked a bit to give more details at a 800x600 or 1024x768 resolution. Well, I'd buy it anyway :-)
3D shooters are NOT the be all and end all of the gaming universe, and turn based games are really handy for the work environment so that you don't get distracted for a second only to find that all of your troops are dead when you turn back to the screen!!! I hate it when that happens - thank god for Civilization 3!!!
