Tiny Towns: Fortune 2 - $33

The smaller creatures of the forest have created a civilization free of predators, and they look to you as mayor to guide their growing and thriving town. However, the area is small, and resources are scarce. The clever use of limited resources will determine the most successful tiny town.

In the expansion Tiny Towns: Fortune, the creatures of the forest have found a way to trick each other into thinking shiny bits of metal have arbitrary value. It's very useful — so much so that you can use this thing called "money" to get other creatures to give you almost anything in return for the right number of shiny bits. If only earning money weren't so difficult!
