I'm not sure if this has been brought up in the past or what the Game Admins' position is regarding the matter but has anyone ever thought of doing a systemic deflation or redenomination of the numbers?
For example, there are some countries where the output is reaching the 10 quadrillions. Why not get rid of a couple of zeros?
This would also make the populations more realistic. The biggest country just surpassed 30 billion people. If we got rid of the last three zeros, it would be 30 million (Or maybe two zeros in this case.) Then the population growth rate would also be proportionately adjusted down.
Above all, it would probably be a bit easier to manage these lower numbers.
