Cheat Happens: Because Game Developers Don't Want You To Play How You Want To Play.
Sad but true. You know, in Fallout 3, I had either 6 or 7 followers. I could selectively move them back and forth from my suite in the hotel and my apartment in Megaton, from wherever I happened to be on the map, using console commands.
Nowadays, you can't even find a console. They have forgotten, or have chosen to ignore, our wishes to try unique things in our games. WTF do they care, they got paid. SMH.
