I think this patch has increased the necessity of commercial and harbor districts, and trade routes with high gold yield. In today's game I just started, I find myself prioritizing settling as close to as many tiles with 2+ gold as possible, even over strategic resources. This is to break even in the early game, to pay city maintenance, before strong money policies like triangular trade. Else, I'm trapped making at least 2 commercial/harbor districts early, and you know, sometimes I like having a holy site, an encampment and a campus first.
I kinda think it's a good thing, because before the patch, so much was production-centric, and income was.. not even really secondary, it just was sorta there. Getting your money right should be a focus of an empire, but if I can't support my 4 legions, 3 catapults and 2 crossbows unless I also have 2 harbor/commercial districts, which I'm somehow supposed to come up with at the same time, things are getting a bit limited. I feel like... I'm playing Rome as England.
Do luxuries and bonus resources need another +1 gold across the board since they had to remove any money for dismissed units? Or maybe just select ones, maybe just luxuries?
