Interestingly, Tom and Geronus, the last post in the Fortifications/Sieges thread in the Background forums talks about exactly this.
Indeed. I think BM lacks what it takes to force us 21st century players to think like those who lived in the dark ages. BM doesn't have as many fortifications as Europe did back in the era as well. On top of that siege battles in BM are rather short. No time for relief forces to break the siege or economic damage to take a toll on both the besieger and the besieged.
