Hello. Is it true that in order for a city to benefit from a tile resource (e.g. elephants -> building elephant workers), that city needs to work that tile? I'm asking this because (to me) it make much more sense for it to provide all of its benefits to ANY city once the resource is linked by road. In other words i'd like to see an "empire-wide" benefit (as long as a road connection exists). From city to city as well. In this case, probably, in order to balance things out, forts and later upgrades should not "capture" resources anymore. Is this something feasible?
