Thousand Parsec is a turn-based space empire building game, as well as a framework for creating a similar group of games, which are often called 4X games (eXplore, eXpand, eXploit, and eXterminate). Some examples of games from which Thousand Parsec draws ideas are Reach for the Stars, Stars!, VGA Planets, Master of Orion, and Galactic Civilizations. Unlike commercial alternatives, it is designed for long games supporting universes as large as your computer can handle. It allows a high degree of player customization, and features a flexible technology system where new technologies may be introduced mid-game.
The aim of this project is to create a free (open source, OS independent) remake of the classic SSI game Imperialism. While the spirit and many concepts of the original should be preserved, it should not become a pure copy but advance the concept in a sense that modern elements of strategic games are included, e.g. of the Civilization series. The game is written in Java using Swing for the user interface. The philosophy is to keep it as simple as possible, use standard/well tested libraries wherever possible and to demand clean, understandable code.
