it would be cool if shop workers, owners, arms dealers, and grocers got a base amount of money from each item sold. right now, furdle and paraplegic are both earning like $5-10 per item because they both want lower prices than each other, and are both so stubborn nothing seems likely to change. you could still reserve the ability to set how much extra you want to charge, but maybe %10 of the price of the gun would go to the person with the shop
(saying this because im thinking about creating a store)
PS some dude named Wiink is trying to make himself a City RPG server right now
