2 other regions have would have more countries than the Balkans. I'm afraid you're thinking about this on a different level than I am. You seem to be looking at the merging of nations as a micro issue, and if countries are fine then they don't need to worry about it or what happens. I'm looking at it as a game issue across all countries. Even if your country is fine, as I said USA is just fine the way it is, merging would be better for the overall game and especially the economy and competitiveness of the whole game IMO.
Why should I play with users from 9 other countries?
