There's been some similar discussion over in the Sump with regards to lowering the income and restricting rare items. @Galtarr had suggested reducing the Trade roll from 2d6 to 1d6. You could still reach the higher numbers but you'd need a high reputation and Leader/Champion bonuses to do so. I suggested limiting gangs to collecting income from only a single territory per game (along with reducing the Doc roll to 1d6x10 so you don't lose too many to critical injuries). I think the combination of these ideas sounds very good on paper, but I can't decide if they would be too restrictive in practice. I do think it help bring back the lower income feel of the old campaign.
