Yes, and make it so that from 2 brahmin you get 10 more every 24 hours so that there will be no more point in leaving your base at all.Go find a use for all the toilets in the wasteland and take your "ideas" somewhere else.
You can already sell and buy brahmin. And "breed" them by just walking around the map and enslaving new ones.It'd be fun to watch how people react if suddenly farming like in facebook app was added for the lulz.Back to topic. A map would be nice. Additional places... There are a few already in the south, dunno about the north.
