Forum:How many followers do you have?

I've noticed a lot of people not being able to get more than the one follower. This I do not understand. I have 3: Dogmeat, Charon, and Fawkes. I used to have SP Cross but she is the only one who wont follow me anymore, because she doesn't like the others. In Fallout 2 they had it so how many followers you can have based on your charisma, I don't know what the max was because I never bothered to get very many. I had a charisma of 6 when I first had all 3 of them as followers; so I do not understand what the issue is. Maybe it's the order you get them in? spawnsos.
