Oh. Okay. 4X. Explore, Expand, Exploit, Exterminate. It’s a genre of strategy game that tries to offer “non-military” winning conditions.

Edit: "I give MOO a XXXX rating because it features the essential four Xs of any good strategic conquest game: EXplore, EXpand, EXploit, and EXterminate. In other words, players must rise from humble beginnings, finding their way around the map while building up the largest, most efficient empire possible.
