Empire is a turn based strategy game of global conquest and diplomacy. The game was originally developed at the evergreen state college in 1974 and was called Civilization. Two members of that development team (Ben Norton and Peter Langston) independently developed new versions of Civilization, renamed as Empire in the early 1980s. Peter's version was developed while he was on staff at Harvard. It was developed using Bell Labs UNIX in C on a PDP 11/45. Ben's version was developed as an Explorer Post project at the Hewlett Packard sales office in Bellevue Washington. It was developed in Pascal on an HP3000. There are many active sites where Peter's version of Empire can be played today. Check the master web page at www.empire.cx. There is only one known site where Ben's version can still be played.
