City mega-improvements?
Hi Folks
On another thread, we were having an interesting discussion on how to makes seiges more interesting. One suggestion I had (in way of suggesting tactics and counter-tactics) was to allow cities prone to sieges to build a mega-project (like in Civ) called "hidden tunnel" or something like that. This would build a tunnel out of the city to a hidden enterance. Benefits might be the continuation of trade, food, and raw materials during a seige (assuming a sieg would be detrimental to these variables). It would also allow for armies or heros to move in and out of the city while maybe avoiding the seiging army.
Anyway, this has gotten me daydreeaming about other possible mega-projects. A full list of mega-project would insure that cities were unique and nations could specialize in certain strategies. Any other suggestions? Perhaps the building of a moat (making normal seige engines useless?), or a very tall tower (better line of sight from the city?), or a zoo (better chance of finding, keeping and training unusual mounts?). What else could we come up with?
