Im sad to hear that, For me in the early version i played long time ago provinces were pretty small and expanding was harsh, it was better to get the most profit of every province before moving to the next one.
Maybe add a VERY expensive building to increase infraestructure for a small amount, that would require a decent time for anyone to actually fill a entire province with buildings, just for those who enjoy making giant citys?
Talking about quality, its impossible to upgrade tradehouses, brewerys, and i never found a spot where i could make a garden, monuments seem to be the best way to go about happiness, who doesnt love a bunch of symbols carved in stone and wood right?
I also notice a lot of lag in the game once i get further on it, and i feel like the game freezes every time it has to make long paths for the traders and raiders to move.
