Stellaris: Modded - Lightfire Union [EP4]

Stellaris is a 4X space strategy game made by Paradox Interactive. And as you know by that developer name, that means this is more than a normal 4X, it's a grand strategy game. I'd say though as far as Paradox's grand strategy games go, this one is probably the easiest. Though it will still make more casual 4X players minds reel I imagine.
