Great Sage
It seems a little unfair to give this ability to only the orcs. Perhaps this should be made a function of the now underused Fort improvement. I was thinking they could get an extra bonus from it, but if their soildiers could build it while other civs still need workers then that would be enough. It would also be nice if a city built on top of a fort would start with walls and maybe even a castle, assuming you have all the right techs.
