Thanks for the sour persimmons, cousin.
Yes, I think so. If it's not what the scene's about, then framing that part too aggressively could undermine the actual action in the scene. That is, if the situation is that Prince John's squeezing the good people of Nottingham through overtaxation while Richard's away at the Crusades and that's also tied to a characters' belief, then I think it's okay to make this part of the framing — it's established as part of the fiction during world and character building. If the scene isn't about the poor of Nottingham, however, then making a big to-do about them could derail play — for instance, if a Robin Hood's player decides to do something based on his belief that he needs to get a new bow so he can take on PJ and the Sheriff, then hitting Friar Tuck's belief about the poor of Nottingham hard at that moment is not great form.A question here is - if the evil overlord is somehow tied to a character's belief, would it be acceptable to use the potential connection between the overlord outlined here as a justification for framing a scene with the beggars? In that case the same could be said for the passing mention of abandoned farms. Indeed failing to mention the abandoned farms upon traveling to the town might be an issue if the players actually latch on to the beggar - evil overlord connection. In this case the presence or not of abandoned farms might suddenly be important, and it might become somewhat strange that that this wasn't mentioned when first passing by.
Regarding not mentioning them right away, I'm less concerned with that. If players aren't concerned with the farms explicitly, then I don't see the need for me to be concerned with them right away, but I do go back to my earlier post that says if the travel scene isn't related to the characters' beliefs then it probably shouldn't be played. And there would be no abandoned farms to pass by at that point.
