Start with 100k Gold and PW:
Start a new game and enter Leemur as your leader name.
When you save your game, include the word multi in the name of your saved
game. Now reload that save. This allows you to see the map and you can change
what other civs are producing, among other things.
Tons of money:
Ask a rival leader for a deal of 999999 (the maximum number of digits) gold
per turn . Regardless of what you give in return, they will give you the cash.
Note: This was fixed in the V 1.19 patch, but should work for all earlier
