Here is what the situation is... My group of heroes have become agents of the Aschaffenburg family and have taken out a loan to buy an inn. They played through the witch's song and role-played well and became fast friends with the DeGoode family and have brought them to their inn (called "big **** heroes") in Ubersriek, Like any common adventurer they have left on quests and missions and left the inn to itself with the family running things.
Now that you have a little back story here is how I am running it for simplicity's sake. Each month the Inn makes just enough to pay for the monthly payments. Then I roll 1 misfortune dice for extra expenses. I roll a fortune dice for the fine cooking and care of the family. Challenge = -1 gold , Bane -50 silver, Success = +1 gold, Boon = +50 silver. I advised the PC's options to help the inn out (i.e. paying a minstrel, a crier, buying or bringing back special foods and drinks) and give them extra fortune dice on the monthly roll for good ideas and money they put into the inn. Also depending on their enemies, reasons and some randomness I can attack extra misfortune dice.
Does this seem like a valid way of handling it? Any ideas to make it better or more fun? Thanks for looking!
