Ages of the Federation is a new total conversion mod for Sins of a Solar Empire: Rebellion. This mod takes place in the Enterprise and Original series eras, focusing on the conflict between the early Federation and Klingon Empire. A resurgent Romulan Star Empire, angry and still licking its wounds after their defeat to Earth and her allies waits in the shadows, ready to take advantage of any of misstep by either the warring powers. The Xindi, new to the galactic stage are also eager to forge their own path.
The most famous Starfleet vessel of the 22nd Century, the NX was Earth's first dedicated deep space explorer. Though Starfleet's eagerness initially led to the first ship of the class, the Enterprise NX-01, to be launched woefully underequipped for the rigors of interstellar exploration, further refinements led to the NX, and the Enterprise in particular, becoming legendary starships in the pre and early Federation era, even though their time at the forefront of Starfleet's technological ability was short.
*Chef's Kiss*
It really is a tragedy that Enterprise ended so soon. The plans they had would have been amazing to see happen.
