Yeah, just having a little bit of politics (kage choosing system) won't be sufficient to call the game realistic. What Xendrus said is great, for exendrusample (see what I did there) you'll need to go to a blacksmith or something similar to customize your weapons. And since it will cost resources you'd have to pay of course and those resources should also be gathered by sending a group of regular people (hireable npc's that do your dirty work) into the mines etc. You'd have to wait for the resources to arrive and there is no way of speeding it up(unlike some strategy games where you build your own village). It makes perfect sense to me, some random guy pays you to customize their weapons and armor and with that money you can either just go and buy resources or pay npc's to gather loads of resources for you. And to get a working space, there could be buildings with a sign in front of it that would say something like: For Sale and some mail adress(some post-bird ID or something). This would allow basic economy related stuff/events to take place and take the reality in SLO to a whole new level imo.
