I bet, if Johnny were to create a sign up list, there would be more than 30 countries. I, and I am sure that a lot of other players, am waiting to closer to the startup to create my country. I made the early placement mistake on Certo. I had to move or be enclosed with the Nodians.
I think a semi-random placement, where we would be basically equally spaced. An idea for this would be to create a series of spawn points where everyone would be on one point. Johnny would randomly assign who starts where and newcomers would randomly spawn on one of the existing points. I do see that grabbing vacant spawn points would be the mission of the day (unless they aren't visible).
Just a thought...
