Open Imperium Galactica (Open-IG) is an open sourceJava^TM reimplementation of theDigital Reality gameImperium Galactica, a popular, 4X (eXplore, eXpand, eXploit, and eXterminate) real-time space strategy game developed around 1996 in Hungary.

The project contains all necessary files (with the permission from the copyright owner Digital Reality) to run the game standalone, there is no need for the original Imperium Galactica files.

¹Technically, Java 7 is enough but running the launcher with it may cause trouble connecting to GitHub due to outdated TLS support in Java 7.

I recommend picking up the latest version fromadoptium.net site.
