this is a minor thing but I think a lot about how RPGs with persuasion systems that let you talk down people's prices basically never reward any form of generosity, even when it would make sense in context (not haggling down desperately poor people for example). It's always treated as "you didn't try" or "you're the sucker", whereas aggressively trying to get freebies out of everyone you meet generally gets you xp. Really creates a specific and perhaps unintentional tone for the player character, imo
