Pointing out that rather than the final frontier, outer space represents one of the first areas of exploration when the power of computers was first turned towards the task of playing games, GameSpot Presents A History of Space Empire Games taking a look at some of the titles in the long-running 4X (eXplore, eXpand, eXploit, and eXterminate) genre. While they are examining history, the article makes no attempt to be comprehensive, pointing out that their list is "weighted more heavily toward recent games for reasons of popularity and more diversity in design."
