This is a fantastic mod with a ridiculous number of features. I'd put it up with Masterwork at the moment in terms of playable races and content. Even if each race isn't a complete overhaul to become something new yet the changes that are there definitely change things up.
A couple quick questions:
Do firearms all use the blowgun skill? I ask because according to the raws it seems that most of the human ones do.
I also noticed that they seem extremely ineffective against many creatures that have some form of built in toughness or durability. Even things like giant buffalo just shrug off the shots. Typically they don't even penetrate the skin. They just hit it real hard and
maybe fracture something. Anything above that point laughs them off.
This remained true even when I started debugging it and made my handgunner corps full blown full legendary humans in all skills with various types of ammunition tested over time, letting them theoretically just smash everything. It didn't seem to affect much. Did I just luck out and get the most roided out monsters in the game world frequenting my fortress or what?
Long Rifles are a good example of this. Looking up the details for this it seems that their ammo tends to not have much heft to it. Even with iron. Which seems to translate to the shots not having much in the way of effectiveness. So that might be why.
Also, Long Rifles don't shoot...Well, long. Or very accurately even. Is there any way to fix that? It was a bit disconcerting to see what were essentially sniper rifles be used as near melee weaponry. I mean, look at this thing.

As it is they have a lot of trouble with maintaining a stable population if you have an actually large number of vampires hanging around. This is because the vampires are...Well,
vampires. They'll suck the life out of all of your ghouls and eventually go all monstery when they can't get their fix.
This is problematic since you're essentially relying on the RNG to determine if not only one but two of your castes (One of them extremely powerful and arguably necessary depending on where you settle.) even get to exist. Doubly so when you consider that ghouls might end up being essential parts of your economy. Not that they shouldn't get fed on if necessary...But it can really screw things up with how it is now.
In the lore the VC's kept humans to do this on. They even formed parts of their army, being peasant levies and all. Might it not work better if there was some type of caste or semi-citizen pet type creature that could act as a preferred nutritious snack?
