Gold has even more uses in Dungeon Keeper:
Dungeon Keeper 2Edit
In Dungeon Keeper 2, gold has the following additional uses:
A Casino set to "rigged" can be used to recoup some of your creatures' wages, at the risk of making said creatures unhappy. When funds are scarce, you can also convert some of your mana into gold by using the Create Gold spell.
Your Dungeon Heart can store up to 16000 gold, and each square of Treasury can store an additional 3000 gold. Gold can be picked up 100 at a time by clicking the golden money symbol next to your gold total at the top of the GUI.
