You cannot get barbs from a goody hut if
- you are expansionist
- or you don't have any military (curraghs count)
- or you pop it hut by settling right next to it.
I have had barbs from settling next to a hut... at lower levels and not with the first city.
I would agree with that....and normal cultural border expansion isn't a special case in any way.
If you had a warrior and settle next to a hut, you can get barbs...
I'd like to see a re-creation of that, 'cause I'm pretty sure I used that technique several times in the game I'm playing now (Maya, Monarch Level) and had warriors kicking around, but no Barbs produced when hut within 9-square city...except city center tile......I thought I saw a detailed discussion somewhere on that..........Maybe it was Oystein's article.I have had barbs from settling next to a hut...
There is no way to get barbs with a town if you do not have and never have had any military. I have popped huts many times with founding my first town. The level does not matter for that. If the hut is just outside the towns borders I sometimes burn the worker move to pop it. This is because I intend to make a warrior and do not want the hut to pop barbs on the culture expansion.
Methinks we are all agreed on this anyways!...I have also had cultural expansions cause barbs...![]()
Chicago
I have a population of 10, and one factory. I am 100% sure I no other pollution causing city improvements. (no Mass Transit nor Recycle Center) According to this sites FAQ on pollution (posted below) my city should only have 1 city pollution for the factory. The population isn't over 12, so why is there 2 city pollution?
Boston
Another example, this city have 4 city pollution. Population is 12, with one factory. I am 100% sure there are no other pollution city improvements. (has Mass Transit, no Recycle Center) Why is the city pollution 4 instead of 1?
How does pollution work?
Pollution, which can be created either as a result of buildings (like factories) or too much population crowding, is represented by orange splotches on the map in a tile. For each population point you have above 12, you will get 1 pollution 'point', and buildings will give different amounts of pollution as well. You can see how much pollution you have in a city by going to the city screen, and in the bottom left looking in the box labeled "Pollution". The more you have, the more chances there is that pollution will occur in one of the city's 21 tiles each turn. Also, you can limit population pollution by building Mass Transit (which caps population pollution at 1) and building pollution by constructing Recycling Center (which limits building pollution to 1).
Which city gets the shields (for city improvements) from forest chopping? Obviously when one city is closest - like 2 squares horizontal vs 2 squares horizontal and 1 square vertical, the first one wins. But what if two (or more) cities are equally close? Does it matter if one or more cities are building city improvements while some others are not, or is it just random?
