Galactic Civilizations II is the best selling strategy game in the United States, has received several awards, and spent a number of weeks in the U.S. Top Ten Game Charts. Endless Universe builds on the epic story, following on from Dark Avatar and Twilight of Arnor.
Thanks to Dark Avatar the different races now have multiple characteristics which adds variety and fun during the game. Now, the races range from "super-diplomatist" to "super-destroyer". Also, Dark Avatar provides the planets with environmental conditions. Thus, the player needs to decide whether he wants to invest into research and development or leave the planet to a hostile player. Furthermore, Dark Avatar presents new scenes, new challenges, asteroids which can be used as mines, new races, and a new version of the spy system.
