• How can my players earn money? Should there be other ways?
• What can my players buy? Why?
• Is money too easy to get? Too hard? How can i change this?
• Are choices about earning and spending meaningful ones?
• Is a universal currency a good idea in my game, or should there be specialized currencies?
