I've been playing adventure mode a lot and this just sort of occurred to me. A lot of the higher level fortress defense civs are comprised of rather powerful individuals with custom made bodyparts (Furies have steelfeather instead of normal flesh, beakwolves have fiendscale (I think that's the name), fiend spiders have fiend plate, ect). Now, a lot of these can only be reliably handled by an adventurer in steel gear or by a pretty developed fortress, which leads me to come to another observation. When Dwarf Fortress starts fleshing out military campaigns and massive battles occur past world gen (battles the player could participate in), these creatures will probably easily overpower the armies of most other civs. Furies for example, essentially have biological steel armor, and don't need to eat or sleep, and furthermore may not even age. They'll wipe the floor with most other nations if any are near them. Same with a few other species. Because wars are all processed in the background in this version, its not really a problem. But once wars start becoming more detailed, something's gonna need to be done to address this or these civs will consistently genocide their neighbors. And that isn't necessarily a good or bad thing but it will certainly shake up the world map and there may as well be a plan for it now. But its late so sorry if I articulated this poorly.
