How do I restart as an OCC?

[Spikey1201]

I was recently given an amazing start and I was wondering whether there is a way to keep this start but start over as an OCC?

Open the worldbuilder, hit save, type something you will recognize as the name.

Return to the main menu. Pick custom scenario and your previous saved WB file. Then check OCC and viola.

The only disadvantage is you will learn who your opponents are. You'll also have some information regarding the map, but in a OCC this may not matter much.
