I've put together a handful of moves for when your PCs are short of funds, and just have to scrape up some jingle. I could really use some feedback!
When you offer promises instead of payment, roll +hot: On a 10+, they're down with it, you gain 1-debt for each point of barter you're short, and you're on your merry way. On a 7-9, same thing, only they want something more: a favor, a little something something, or a bigger debt than the value you're receiving. On a miss, no dice, and you've pissed them off.
When somebody owes you, you are always considered to have leverage when you manipulate them, and you may choose to roll +debt against them instead of +hot.
When you're in debt, at the start of each session roll +debt (if you owe more than one person then just roll the highest, you deadbeat). On a 10+, they're looking for the full value, right now, and they'll do whatever they can to extract it from you. On a 7-9, they're willing to let it slide for a bit longer, but they're going to want something for their trouble: a favor, a little something something, or maybe a down payment. On a miss, they've got other things on their mind, but they'll get around to you eventually.
You know I'm good for it: (Operator playbook move) whenever you offer promises instead of payment, you always succeed as though you had rolled a 10+. If you attempt to use this move on somebody you already owe a debt, you are acting under fire.
