Andrey’s Technologic Empire
The original empire of Andrey Taskiv, the technologic empire earned fame as a focal point of science and technology in the community. He’s also best known for his use of the color Green. Andrey is also one of the best players in Space Empires III that I know of, so in game his empire was just as formidable.
Shane’s Nloam Empire
Artist Shane Watson since Space Empires 4 has proved to be more than capable with his contributions to the original set of SE4 race styles and art. Afterwards, he released a couple of race styles for the game and, if memory serves, went on to supply some art for Space Empires 5.
The Nloam empire is one of the best produced sets showing you can have consistancy among variety in a race style.
