Jullian Gollop (designer of X-COM: UFO Defence) tells how X-COM was created: said:
The project started reasonably well with myself and Nick designing and programming, while the art was to be done by John Reitze and Martin Smillie at MicroProse. Soon we had some problems because Microprose did not understand our game design and they asked for clarification. Several documents later we were not much better off and I had wasted a lot of time. Certain creature types were removed, including the 'Men In Black' and others added. Then the whole project was nearly axed when MicroProse made some cutbacks due to financial difficulties. Everything proceeded reasonably smoothly for a while until Spectrum Holobyte acquired Bill Stealey's shares in the company. Our producer was made redundant and the game was nearly axed again. Finally we had to spend a couple of months working very long hours at MicroProse in Chipping Sodbury to get the game finished by the end of March in 1994.
Now, there's 2 reasons I'm posting this... First of all is that it shows that it has never been smooth sailing for X-COM, even from the get-go... And secondly, it confirms that the game was, in fact, finished at the end of March, 1994!
