I know Vader has played this game, and that it has an FPS coming up soon based on the world (if not based on the original games), but I did not know there was basically one guy behind it, Richard Gollop, and what other games he has made.

(X-Com was released as UFO: Enemy Unknown in some regions).

So I'll go straight to the surprises:

Rebelstar: Tactical Command

and

Gamers TM, Issue 108 has a six page feature on Mr. Gollop. He started out with his first games published in 1983 on the BBC Micro, and all of his games have been turn-based strategy games (which the magazine credits him as a form he invented).

He also made:

Which he considered a "semi-educational" take on the most famous strategy war game (chess preceded X-Com by a few centuries).

Some quotes,"The most successful turn-based tactical game is Pokemon, which is one of the most successful franchises in existence.  Although it is pitched as an RPG, the combat system is pure turn-based action with some strategic meta-game elements. In structure I would even compare it to the early X-COM games".

"Fallout 3 managed to include an interesting hybrid turn-based real-time combat system. Some more innovation like that would be good, and Fallout has proven it can be commerically successful. But this is the rarity.  I am not sure which direction the Japanese SRPGs are going at the moment and whether they will retain turn-based elements.  I hope for some more innovative games like Valkyria Chronicles."

Mr. Gollop also tried FFT. He said it came off as "too much like work" -- which is funny as that is what I always say about Real Time or Turn Based Strategy games.
