So i have come across 4 followers now, but i already have 2, and it says "Come back when you have room for me".
I heard you can tell your followers to stay somewhere and that you can get them all to hang out in one room. ... i have the novac hotel but my followers wont stay there?
is there another home i have to aquire?
You can only have 2 followers at a time,
the others remain where you find them so take note of thier positions,
just tell the ones you dont want to go away they return to where you found them (or tell you where they are going) then select your new char.
Spoiler you can have 4 followers,
number 3 if you are friendly with ncr they give you a radio and you can call for help this person stays with you till they die then you can call for help again,
number 4 only in new vegas you can hire a bodyguard.
