My Milky Way Galaxy is a mod designed to create a more immersive experience for the player. I've renamed some of the factions to give them more formal names, such as the United Terran Federation or the Altarian Star Republic. I've also adjusted the size of some of the planets so that Earth isn't nearly as big as Jupiter. Additionally, I've added a new faction to take the place of the Snathi because... well I like squirrels and do not want to see them as villains.
The new race I've added is known as the Galrisian Confederacy, a feudal society wrestling with internal conflict but also having a martial, yet honorable, nature.
This mod includes eleven maps of the Milky Way Galaxy, one for each major civilization. This map also includes an active galactic core and I've included some of the actual stars in Sol's stellar neighborhood... for example the star closest to Sol is Proxima Centauri. 
I hope you guys like it!
I also want to give credit to some of the other great modders out there whose work was included in this mod:
