Det enda jag har hört om det som kommer nära är kompletterande regler för Pathfinder -spelet. Jag äger Ultimate Campaign boken som har regler för kör ett företag som en del av dess Nedgångstid regler relaterade till Kingdom Building :
Run a Business
If you have a building and that building generates any kind of capital, you can spend 1 day of downtime working at your building—increasing its productivity by inspiring your employees to work harder, using your expertise to get more done, or using your fame to attract more customers. This counts as using downtime to earn capital (see Gaining Capital), but you gain a +10 bonus on your check.
The capital you generate must be a kind that your building can generate. For example, an inn that generates gp and Influence can generate only those two currencies using this downtime activity; you can’t use it to generate Goods, Labor, or Magic just because you’re personally running it for the day. You must earn capital acquired in this way as normal.
Dessa är valfria; Gamemaster behöver inte inkludera Kingdom Building i spelet.
