Legend
A type of video game - ""eXplore, eXpand, eXploit, and eXterminate". Like Kingslayer for Pathfinder, if you played that.
It's been a wargame term since the 80's, or perhaps before. Starfire was billed as a 4X game on the nets in the late 80's, as was Kings-n-Things* (* massive list of & ___ follows), Godsfire, Lords of Space, and more. It wasn't until the 90's that I saw it used for computer games. Lords of Space even billed itself as a 4X game, and it was a 1986 or earlier release. (I was running a game of it my senior year in HS.)
