Its always good to confirm the progress is noticeable (and helpful). Thank you.
I have also noticed the R:C ratio problems. I guess a lot of people
just live at the office :). I will massage this ratio for the next
release in favour of residential.
Regarding building height limitations, I would prefer to skip the city
population dependency and directly implement a more dynamic
relationship with land values. I mean, in theory anyway, tall
buildings build only in areas where the land is so expensive that you
need a lot of "renters" to justify the cost. Obviously, city
population indirectly affects this land value as land value in a way
is just "demand" for that piece of land. But I would prefer to tie
building heights to land values instead of imposing somewhat
artificial constraints on the heights.
