i put the siege tower at 110% working i will make a siege system like i normally do in stronghold2
HOW IT WORKS
first you arrive whit your troops and lay siege
after you begin to build the siege camp designing a few troops for it (creating new party named siege camp)
will take 9 hours to build the siege camp ,the enemy my try to attack so be near to protect them
after building the siege camp the faction town will be changed to "under siege" and slowly will lose suplies
if the town come whitout suplies he can either a) sally forth for attack b) surrender
during the siege you will be able to build siege equipments the siege camp will assign half of their troops for it and during a siege you can leave and go away because the
siege camp will keep building things
the siege camp also will need suplies you can send them suplies by either a) talk to the steward to send caravans b) bring them yourself
wen any of the siege equipments are done you will be able to take a few men of the siege camp and use that siege equipment (don't take them all because if you made this you will break the siege on one side of the city and them allow caravans to supply the city
you can program the siege camp to attack after few days of besiege or after the siege equipments are build
cities will have villages you can either A) burn them

B) loot their suplies and leave the siege C) use them to build siege equipments D) use them has farming villages (has the risk that the enemy eventually take a few suplies)
