Playing an unmodded DA game at Suicidal, largest galaxy, most planets, 7 AIs and 7 Minor AIs.
The Paulos (a minor AI), have declared war on the Jessuins (another minor AI) and even the Altarians! Even the Scott-whatever AI is at war with another minor AI. The Snathi (another minor AI) declared war on one major AI but eventually surrendered to it.
The minor AIs did not just declare war, they have fair warships prowling the space lanes! Several of them! Even small fleets!
I don't know how many DA games I have played (many hundreds, anyway) but I have never seen this before!
