The first workshop repair unlocks a basic tool and a nearby route.

A reward that opens something new.

A reward changes a number, but leaves the next session feeling the same.

Build an economy.
Test the assumptions.

Work with Twill on resources, rewards and monetization. Model currencies, sources and sinks, upgrade costs, premium pricing, in-app purchases and DLC. Keep the assumptions editable.

This asks the player to return 3 times before the first repair. Is there enough reward along the way? Try a lower cost or a different gathering rate.

Who will recognize the appeal?

Start with relevant games and the people who play them. Examine which parts of your design matter to that audience before committing to a regional plan.
