Features of Distant Worlds Extended Universe
2 new Avian races.
The Yl'ta

Designed by PrismaticFlux.
The Yl'ta are an extremely cautious, slightly aggressive race. The Yl'ta get lower trade income than other races but have extremely good ships and get very high bonuses for certain rare luxury resources. They seek to explore the galaxy, to collect it's history and rarities.
The Banoserit

The Banoserit. They have exceptionally good eyes, and a large part of their brain is used for their optical sensory input. They can use this ability with some research to scan space at long range, beating other races Long Range scanners by far. The Banoserit will be able to see ship movements much further around their empire. The Banoserit also have their own government type, Authoritarion Eugenics. It is acceptable in Banoserit culture to remove unbeneficial genes from the gene pool and to encourage the breeding of beneficial genes. This government type gives very good bonuses however the population will expect a very high reputation to be held by the empire as they hold their government's behaviour to a high standard.
Distant Worlds Extended Universe also introduces many other unique racial technologies that further define different play styles and differences in enemy empires. There is 2 new unique to 2 races weapon types with their own art work and in one case sound effect.
The Galactopedia has been updated with all the additions so the experience is as well integrated as the base game.
Technolgoy items that are researched for wonders that can only be built by 1 empire now also give a small bonus so they aren't completely useless if you are too late.
The mod has also received many hours of testing for balance and playability.
Das and Larry Monte have been given preview versions as they have shown interest in doing a Let's Play or preview of the mod, and I have enjoyed their videos immensely in the past.
