Must be code issues, or due random that lead to it. I think there is more number of white male and female more than dark skins people at start, then they making babies to overwhelming, but it's similar to faction, faction and clan can get wiped as well. If player try to kill other faction or clan off, what is difference of it got wiped out since this game designed to be war and conquering mostly?
I see nothing wrong because this game is war game based mostly. Now if it peace game, then I can see issues, and yes, that would mess up, but can be this game be peaceful in united? I don't know, other than there is 300 skill trade to buy town without war, but other than that, they didn't design or add for peaceful mode yet, I wonder if they could do that add gameplay other way to play by united whole faction or make all faction peace together to win game or something, rather than old way of conquering.
I don't see any issues unless they add peace mode gameplay more than mere war and conquering, then we should worried about that issues.
