Money During Long Periods of Downtime

If the PCs have a very long time between adventures, especially years, they have the opportunity to collect a great deal of credits through downtime. Use the guidelines for average progress and the Cost of Living table to figure out how much they get. Because you're trying to convey that a long time has passed, have them spend it before you jump to the end of downtime. What did they invest in during those years? What drew their interest? Did their fortunes rise or fall? Did they acquire interesting objects or hire compelling people? Consider this expenditure another way to show how the PCs impact the universe.
