More then one follower could be pretty awesome, maybe a little hard to manage but still full of advantages. I was thinking along the lines of a perk. What do you guys think? I also hope there's a bigger range of followers.

You can have 2 followers, but one has to be an animal, the other humanoid.

On Fallout 3 you could walk with Fawkes and Dogmeat at the same time.
