Damn, I should have read this thread before choosing my territory . Less than a million in total Irl population.

As a suggestion, could territories have buffs and debuffs? For example, if an army for Asia attacks a territory in north Russia, they should be handicapped for being in a climate inhospitable to them, same with cold countries attacking hot ones, like Africa. And if that's the case, if an un-native army (let's say Asian) takes control of a icy territory (north Russia) they should experience a debuff when defending against nations native to icy territories. Just an idea, you may not like it but you could see it as a bit of realism.
