Since Toady seems to not be blueing things on the dev page, let's speculate about what stuff will become blue or purple upon release.
"Grazing and Drinking for Livestock" should already be purple already since grazing was added in fort mode, but it isn't.
Under Markets:
"Small markets associated to entity population villages" should certainly be green by the time this is done, although I don't know if Toady's done everything he wanted to with them yet.
"Markets need to replenish goods and manage ownership changes" may well be green too. I don't know about ownership changes.
Under Villains, we could get some purple from necromancers.
Under adventure sites:
"Non-town sites need to created and used for various purposes in world generation (prisons, tombs, temples, mines, castles, etc.)" should be purple, we'll get everything but mines added.
Under Night Creatures and the Undead:
"Replace skeletons and zombies with generalized generated types of creature corruption/undeath etc." I think should be green. If Toady considers some not yet completed night creature stuff to fall under this, it'll at least be purple.
"Causes -- existing from the beginning, death circumstances, being cursed, focusing on specific historical figures at first" purple
"Goals, if any, as individuals, even if it is murdering or mutilating wayfarers in the woods" Vampires have some of this, so purple.
"Weaknesses, restrictions on movement, other limitations" Purple. No restrictions on movement yet, as far as I'm aware.
Under Torment the Living:
"Night creatures must act out their goals during play" I think green
"Some victims can end up drained as subvillains or slaves in the same way a bandit leader has subordinates" I think green, at least purple, because vampires.
Under Curses and Exposure:
"Can be cursed by night creatures when you put them down" probably purple since I think Toady wanted to do more with this.
A couple questions that arose from rereading the dev page:
Will we get population sprawl with farms and whatnot growing up around adventurer-created sites?
I feel like that should happen based on the adventurer's reputation and what stuff the site actually includes.
Will merchants come to adventurer sites?
It would be a good reward that makes sense for building a nice site, both traveling caravans like in Dwarf mode and potentially markets formed by the population.
