I would like to be able to actually Siege a city, not just watch from outside the walls, with my army standing idle for three years, I wish I could build fortifications and such to actually prevent the ennemy from fleeing (which is implemented already but has no visual explanation).
This could be easy to do : just an option while laying siege to a city/fort... : in the menu where you build siege engines (rams, sapping points...), just allow the building of wooden walls and maybe towers all arpund the city to help when the besieged army tries to get their way out. Maybe only allow this with big cities with stone walls, so as not to have better siege camps than the community. Oh, and make this require a huge amount of building points.
This could really be cool to have when you don't want to assault the walls. The Romans actually did this in a number of occasions, and I am pretty sure they were not alone.
