Is there any way to lengthen the duration of a siege? I find this an annoying feature in that you can build a fortress and unless you man it with 25 peasants it still falls after a couple of years. Surely a small city of this size should resist starvation for a decade even with a sizeable defending force. It would also justify the creation of siege equipment which is currently rendered more or less irrelevant. I always try and role play storming the castle rather than parking an army outside for 3 turns.

Thoughts, anyone?
