So i've played about 5 games today with fanatic purifiers. 600 star galaxy, 20 empires, no advanced starts, with FE's.
In all of them, I've managed to get a toehold (some bigger than others) before getting smashed by a giant federation made up of half the galaxy, who have at least five times more fleet size than I do.
In my other non-purifier games I've also ended up surrounded by hostile federations, it doesn't feel like empire vs empire, but empire vs federation, and the only way I can survive is if another group of enemies has teamed up but attacked the federation first.
