1. Egypt
With a Republic of Egypt declared in June of 1953, and with a few years until Nasser, Egypt is in a unique and transformative stage at this time. Furthermore, the Middle East is always full of fun characters and player interactions.
2. North Korea OR South Korea
I have always been fascinated by the Korean peninsula in the postwar era. I loved playing North Korea briefly in Max's 1956 game, and I would be glad to try it here. On the other hand, South Korea under Rhee and before the Miracle would be fun too. Whichever one you want filled, I'm game.
3. Anything else you need.
