Hmm... how to answer that without sounding like a preachy fanboy.
Maybe its just me but I kinda liked skulking around in couple of sections of the medieval city with the freedom to rob, knock out and kill whomever I wanted. Sort of made me feel more like a thief, be it a slightly psychopathic one, than a male non-acrobatic version of tomb raider with shadows up the jacksie and a green glass eye.
