Imperialism is a now freely-downloadable turn-based strategy game for Microsoft Windows and Apple Macintosh computers, developed by Frog City Software and published by Strategic Simulations, Inc. ("SSI") in 1997. In Imperialism, the player is the ruler of a 19th-century Great Power (one of seven), and aims to become ruler of the world by conquest or by vote, taking advantage of the Industrial Revolution while moving to world dominance. Random maps do not represent the real world, and most of the territory names are made up. Multiplayer or single player against computer nations.
