The number of profiteers will be
extremely limited.
There is a mission system in infancy I have richarded around with, but never finished. The amount of GUI work would be immense. I have other things above it on the priority list, like a scrolling toolbar to accommodate 100+ inventory items, a dynamic map, etc.
If the mission system gets off the ground, sure, truck drivers that get jobs n stuff would be neato burrito, but until then, people have to buy their own trucks.
