V 1 - All possible events can happen, possible meaning that there are enough resources for it, that it is possible with real-world physics and conditions, etc. etc. Players should be able to freely choose between all possible events. The player controls his country through absolute, godlike means and should be able to completely, 100% control its path. Of course everything he does should be done in small, possible steps but as long as the steps are small enough and are done with enough effort everything should be doable. Long chains of possible (but still unlikely events) that lead to a great deviation from what would the most likely future of a country IRL should be allowed. V 1.5 - All possible events can happen, as long as it does not lead to too great a deviation. V 2 - All likely (instead of possible) events can happen, likely meaning that there is a significant chance that it might happen (if I would arbritrarily choose a number it would be 33% of the time) Players should be able to freely choose between all likely events. The player controls his country through the means of the actual leader of the country and should only really be able to control politics. This could never lead to great deviation from what would probably happen IRL. (credit to /u/eragaxshim for the descriptions and classifications)
