well, i agree that we should have some more extra game after finishing main story (after all, in epilogue it is mentioned you were promoted to mayor of taht vilage or something about that lines) and it allways annoyed me when i walked into mages guild and still sow my title just poor journeyman.
i will love if it gives you just little more options, like extra special slaves just for you, acces to special merchandise at market..etc.
but whole idea about turning it into empire managmenbt game ? well no. what are you basicaly sugetsing is that to degrade MAIN QUEST to just..chapter 1 n many chapers of world conquest...but why ? nowhere in game it want hint that you are power hungry person, well mayby if you sided with tha hayes or how is called that bad guy, it should give some credit but thats all.
