Whats up with keeps having SO MUCH unused space, along with goblin towers and kobold forts. I enjoy goblin and kobold towers better, because they have a somewhat labyrinth aesthetic to them, as do dwarf forts. Also, if you stayed in a town long enough, could you watch them construct houses, temples, shops, etc? Will Toady ever make it so that the AI towns have to WORK for there material, instead of having it magically appear in the shape of a massive Keep?
I: Store resource counts at sites, controlled by map properties and world gen professions, and in armies (Core38)
Being worked on currently.
And then there's all this:
# II.A.1: Realization of guarded tribute caravans from existing world gen tribute relationships (Core81)
# II.B.1: Ability for civs to enter into trade during world gen (part of Core3)
# II.B.2: Realization of trade caravans from existing world gen trade relationships as traveling groups on the world map (part of Core3)
# II.B.3: Control inventory of shops in adv mode based on trade and available site resources (part of Core42)
# III.A.1: Replacement of generated caravans in dwarf mode with actual caravans (part of Core3)
# III.A.2: More interesting trade agreements and diplomacy in dwarf mode based on actual world situation (Core62)
# III.B.1: Addition of bandit groups which harass caravans (part of Core71)
# III.B.2: Ability to be a caravan guard in adventure mode (part of Core65)
This is all "coming soon" type stuff.
For the most part, this stuff is everything you're talking about there.
The "watching" them construct stuff is much, much later, though.
