Playing the Market is a system-independent supplement for any RPG with a market system where characters can go shopping for gear. Rules are provided for both fantasy and modern/future settings.
The basic mechanic for Playing the Market is for the game master to roll a handful of d10s. The number of dice is determined by various factors, such as the population of the town the characters are shopping in, or how well connected their fence is. In general, low values determine availability of the item they’re looking for; whereas higher values tell how much it will cost or how long it will take to obtain it.
Playing the Market is available as “pay what you want” exclusively at DriveThruRPG.
