Silk Daddy is a pimp. He likely doesn't care about what a girl can do other than sex, so maybe his common stats grow more slowly. Milord has a good education, so maybe his common skills grow faster as a result. Might also make sense seeing as Milord is "easy mode." General differences that fit the lore.Not easily.
Along these lines, any ideas for the other normal starts to give them more flavor?
Maybe make it harder to develop strength above Healthy / combat skill above C- for the less physical backgrounds? Maestro, Doc, etc. They aren’t warriors.
Maybe make it harder to develop skills outside their “speciality” in general?
Maybe give them special deals: free exams at hospital (Doc), free theater tickets (Maestro), bonus pay for public use (Silk Daddy), etc.
I think deals are a good idea. I also think that making the skills outside of the character's specialty harder is a good idea. I agree that non warrior characters should have more difficulty raising combat skill and health beyond a certain point. They would have had no reason to before.
