Investing Gold in your Empire will give you an hourly income, which will continue to accrue even when offline! The more land and buildings you purchase, the greater your income. The bigger your income the better your inventory can be, and as you climb in level and unlock new locations, you'll gain access to more Empire you can purchase. They'll cost more to buy initially, but they'll produce a larger income.

Something to remember: the higher your income, the more other players must pay if they want to Bounty you!

Some items have an upkeep cost which will reduce your total income. Keep an eye on these numbers to make sure you don’t end up paying more in upkeep than you earn!

If you end up with a negative income, you have probably overspent on inventory that requires upkeep, and had better start selling some off before your Gold runs out and you end up losing them to your debts.
