Comment 2 for bug 1516785

Or maybe the limitations should depend on gametime - but all this would only bring complexity to this.

I suggest configuration like this, f.e. in smelting_works/init.lua

   aihints = {
      prohibited_till = 400,
      easy_limit = 1,
      moderate_limit = 3
   },

This is trivial configuration, everybody can tinker with it.

This should not stop expansion, only make it slow... and it would simulate poor player that does not have enough buildings of some type.

Of course, I would do a lot of testing with AI and compare teritorry expansion and military strength (during time) of various difficulty levels.
