A brand new mod just came out called Star Trek Vs. Star Wars. This mod is only compatible with TA. It replaces all major and minor races and each race has its own unique ship style, Tech Tree and Planetary Improvements. This mod focuses on conquest victory so you start the game with most of the techs enabled. This mod includes components already made from kryo, AF_Ronin, and Master U.
