Balance of random opponents - 5 hive minds in game

[mudakonn]

Started normal game with myself as a hive mind and for now I have contacted 7 AI opponents 4 of them being hive minds as well...

On top of that one neighboring hive mind decided to be my vassal and...is harming relationship as diplomatic mission while being 100% loyal.

Well...and they declared on their neighbour fananatic purifiers war - however I am not called for help. I see that my vassal has destroyers while i started producing cruisers so is AI assuming me declaring war to their enemy as well or they will call?

Anyway - I lended them my destroyer/frigate mix fleet for free:)

PS. I play with no mods and Ironman cadet difficulty and have not declared any wars

Whether you get called into war when a vassal enters one depends on the type of war and the vassal contract. Default is defensive wars only, so if they declare an aggressive war by themselves, you are not part of that war.

When it comes to the types of empires that are spawned, there is some normalization, but it's not very strong overall, so you can get quite lopsided galaxies. Hives / Machines tend to be especially common if you lack the DLC for the other, since both use the Gestalt "Ethic".

I dont have any machine type DLC-s so maybe that is why hive ones are prevalent or it is just a coincidence - yes I checked vassal settings and can change their agenda but I am OK them fighting the purifier scum.

IF you would be called to a war, it'll be when it starts. Depending on your Overlord/Vassal Agreement, you may/may not be involved in their wars automatically. YOU CAN still be included if you arent by default involved, BUT they still got to invite you.

As for galaxy empire generation, the AI TEND to be spawned somewhat similar to your empire, or opposite. If you are Megacorp, you'll find a few more empires that are ALSO megacorp. If you are Fanatic Xenophile, you'll probably find more Xenophobes. It appears to ere on the side of "whichever would give the player some challenge", but NOT ALL empires will be this way. Just that whichever YOU are, the galaxy will generate empires that are at least in some way a challenge.
