Mesmetron Shmesmatron! All you need to do it knock your target unconscious and slap a collar on them while they lie there helpless.

The most I could see them doing with this, is putting in a slave that is a follower. That's pretty much it... (IMO.)

I'd like to see better slave infrastructure in this game. The slavers of Fo3 weren't done well in my opinion. Since Caesar's Legion is in this I think slaves will be a bigger and better part of the game whether you are a slaver or slave freer.

I think there should be slaves, and not just companions like any other kind of companion. But it'd be nice to have slaves that perform similar tasks to Wadsworth or Godfrey.

This is an interesting idea. I think owning slaves should be an option for characters that sides with Caesar's Legion. You can use them for your own purposes and interact with them. Depending on what you do to them, they can become your loyal companions or even friends if you treat them fairly and kindly. But if you mistreat them too much, they will try to escape or even kill you.

I wouldn't mind buying slaves to use for testing the weapon mods I create.

LOL I had more of a kirk douglas in full Gladiator armor in mind Like the Caesars Legion guys, without the helmets, leading the Slaves to FREEDOM!!!

Edit: that pic looks more 300ish

If implemented it could be in a way similar to the Hla Ood Khajiit slave quest in Morrowind. You'd get paid to successfully deliver slaves from point A to B. I wouldn't mind generic NPC slave purchases either (siding with CL and all).
