InEffect: it's actually really hard to say what part of kingdom management is bugged and what works properly, or I would document kingdom development and added to the guide. the whole thing seems more like a way for you to dump your gold than anything cause it moves at a snail pace otherwise and income is too slow to do anything without buying BP.
Yes, at the beginning you do not have much. The first good income boost i felt, was, when i took this 1500 BP project, which gives you additional BP for each region. At early game, i had like 25 each week, when i got my kingdom, as they stopped the 50, they gave me before. Now i have 150 each week. At the beginning, you have to put in most of your money to being able to do anything.
But i would wait, if i were you. They are just testing out, what they should implement, or not, as i have seen after the last patch. In one instant, there were like 15 region based project in one day. I am pretty sure, there will be more in some later patches.
In my case, i will wait for some time longer, a month or so, before starting a second play-through. At the moment, a lot of players in steam claim, that there are new annoying bugs in chapter 1-3, because of the patches. and i just hope, that they will have been able to fix most of it in a month from now on.
