So yes, in my opinion Barbados could dissapear, but not the player himself, he can join another countrie to play.
Lets say the one closest to him on the map
True. Or, we could get people from countries near barbados and add them to barbados, countries not yet playing but lets say the closest ones to him on the map. I suggest Martinique and St Lucia to start, which would double the allready existing population. No changes, no adding of countries. Boom, finished. However if we remove barbados we have to add another country, or subtract one.
