Note: Characters who receive income for having certain types of districts in their cities (the King, Emperor, Bishop,
Abbot, Merchant, Diplomat, and Warlord) may receive the extra gold at any time. You may receive your income either
before building new districts (if you need the gold in order to build the districts), or after building new districts (if the
newlybuilt districts give you income). All income must be received at once, however. If you receive income at the beginning
of your turn, you cannot receive additional income from any districts you build during your turn.
