Yes, the base score is what determines the number of people; there is a limit to the number of followers you can have per base.
Anywhere i can see these 'base points' ? I'd like to get more followers, but i don't know how. I just now got my first one.
The little house in the top left is you base score. Every 225 (I know very arbitrary) you get a new one up to 10. You need to make sure you have beds for everyone though. That includes you and the NPCs you find/hire.
Also I haven't built in the 'live' spawning of them yet. You'll have to leave the base and come back to get them person to come.
Hiya, thanks for your reply. Been enjoying the game so far.
Another quick question though, what would be the best way to increase that base score?
