Set all powers to 1000 IPC bid. Then make all powers except one of your choice hard AI. Use edit mode to make all the powers at war with the power you’re playing as and make everyone else allied with each other. Put all neutrals including true under custodianship of all powers. Get rid of unit placement restrictions. Give only your power you’re playing a 999 IPC bonus and 999% income in resource modifiers.
You win by conquering the entire world.
It’s crazy, but if you like bonkers, this is for you.
