Last playthrough I had multiple settlements with 30+ whiners... I mean settlers. Keep in mind, Im modded and it was one of my mods making that possible. If I recall correctly, the typical settlement max should be your charisma +10. So max would be 21. Not sure if that's changed due to the DLC's.
God mode? That's no fun.
I like dying over and over and over and over and over and over and over because I stumbled across a bunch of supermutant Overlords packing 20mm cannons.
Zuhl, I envision something a bit less... imposing and more sprawling for my Spectacle Island Fortress of Duk. Im still working on Vault 88. The main part, whiner quarters and what not are done. Just adding the rest of the infrastructure.
