Is there a chance that we will see some changes to town and building generation sometime in the next update/s? The world of DF is truly massive, but towns, fortresses etc. completely lack any flavour - taverns, for example, are just some simple furniture, sometimes a bartender, some drunks, they never feel realistic or alive, and they're always too similar. This makes the adv mode rather unappealing.
Have you considered tile generation like the one used in Cataclysm: DDA? That can create simple variations (it has several thousand basic types and subtypes of buildings with different combinations - like ground floor A, combined with first floor B and basement C, with loot generated from appropriate sets, like house, shop, restaurant, petrol station - so it's always realistic). It combines simple house layouts written in simple code, to create cities that feel very realistic - kitchens always have appropriate cooking equipment, food, drinks, bedrooms have clothes and sheets, bathrooms are very random - some have medicine, some have drugs, they often have basic things like soap or razors. It's all rather simple but the effect is unlike any other game.
I think that DF would instantly become a very different and a much more advanced game with something like this.
EDIT: I'm not a programmer, but I can make several realistic-looking locations for Cataclysm in a single day. I think that something like that, perhaps using JSON like Cataclysm, might make things easier and faster for Toady.
