Look at genetic age mod. I belive there is something similar to listening node
Indeed but both are below ground aren't they? What we need is a better name for the improvement that is better than a fort but not as good as a command centre.
I also found "Pillbox" as a special bunker type.
Maybe we should get rid of the fort on top of it and just adjust the cave graphics (if possible?)
A few thougts on observation towers
I've built a wooden watchtower outside of my cultural borders, close to what become my second city. Fortifying the tower it upgraded as intended, to stone and then steel, now it's upgrading to radar station. My point is: it is too early to have similar towers! I just researched sedentary lifestyle and I own a steel watchtower, and in a hundred turns of so (see the attached pic) I could be able to own a radar station! In my opinion, the upgrade should be possible ONLY if you have researched the tech where you can actully build that tower (steel for the steel watchtower, radar for the radar tower and so on).
Another concept/request: can we have properties spreading from towers and/or forts? I'm pretty sure mines increase air and water pollution, so this could be done right?
In my opinion they should:
a) reduce crime: if you have a sentinel on a high tower, it can easily detect people who are doing something illegal
b) reduce flammability (possibly only in modern times): you have a tower with a sentinel, it's more easy for him to see a fire
Towers on resources?? I can build them anyplace?
Of course you can. You just wont get the resource under it. Or you shouldn't. I think you still do for the forts.
@Koshling There are a problem with the Super Forts merge to do with the distance between forts. Basically it treats cities, forts and towers as being the same thing so you can't build a city near a fort which is the biggest problem as you should be able to. You should even be able to place a city on a fort.
So the best thing to do then is build a tower, then build a fort on top of the tower, that way you get the resource?
You can't build forts within two plots of each other. What is wrong with building the normal improvement?
