This change looks amazing. I think this will make large empires a lot more interesting to play. In my current Dutch colonial empire game, it seems that I spend far too much time spamming the button for forts, workshops and marketplaces every time I have a bit of cash, and also scrolling down the province decisions list hoping a new decision that isn't Establish March or Yearly Provincial Festivals appears. This change looks like I'll have to put a lot more thought into my buildings and decisions, which I look forward to.
I am really hoping there are less no-brainer decisions and a lot more cost-benefit analysis of one building compared to another. It looks like it's going that way, so I'm pretty excited.
And I never really looked at the city view anyway, so I don't care at all about its removal.
