[2023] Watchtower Idea

I had an idea for adding a watch tower building in the game. The watch tower would be able to make enemy cloaks visible when its standing adjacent to it. Only 1 watch tower can be build per city and you can place it anywhere (maybe if you want to nerf it you could make it so it could only be placed on mountains, which give mountains extra use if they dont have any gold on it). It could be a cool introduction to non- population/income increasing buildings.

Would also make cloaks less annoying without nerfing cloaks/daggers
