Better:
1. Ask NPC for Caravan Job, or NPC for Raider/Slaver job
2. Get job
3. Go out in wastes and defend/attack caravan, that may or may not have other players present
4. If you and the Caravan leader survive, or if you and your raider leader survive, earn 1000 caps (100 is a JOKE.)
no need to further complicate
The more players, the more guards/raiders.
