An interesting fact about X-com: Ufo Defence (or UFO: Enemy Unknown as it's know here in Europe):

Know any people who told great stories about winning the game on super human (the highest difficulty)?
Check if they know what Xcomutil is.
If they don't know they probably didn't play the game on super human because the game has a bug that changes all the games to easy if you save and load!

Xcomutil was made by Scott T Jones, a devoted fan, and corrects this problem (among adding features and correcting other bugs!)
Xcomutil still being updated in the year 2001. 5 years after the release of the game!
