Well at least your admission to dealing little with "newbies" makes me understand better why you chose certain stances in your vision of what BM needs to be more "fun".
Low incomes should also be expected for certain realms. Obsidian Islands is a prime example. But for your Dwilight experience, Barca will never reach any good income, even at maximum production. Poor cities, no nearby townslands, poor woodlands and rurals, means if they have enough knights to maintain enough estates for all those regions, the income would be spread about paper thin.
If anyone ever decides to be crazy and try to go for Sallowtown, it's a similar story. The city has about no income or food production, nor do its regions either. It is separated from easy access to fertile grounds by a huge desert that has stats fitting for a desert, minus any potential wealth from oil, so in other words, poor and barren. Then there are those mountains, and before you think that those mountains at least would provide good gold income, they don't. The Divides all barely make it past 100 gold base. And at least one of them has base food production in the single digits.
So yes, sometimes there just isn't any choice if you decide on the wrong realm. Of course you can say all you want about having outside support and all that. But really? What realm is seriously going to give you food for free, or at a very low price, especially when your entire realm would be dirt poor to afford any food, yet still needs it? I'm talking about theoretical Sallowtown realm, by the way, which some people apparently think they have it figured out.
Ahem...they probably don't.
