The VERTEBRATE variation will, I assume, include the male and female castes; is there some way to tell a creature to delete castes from a variation and make new ones, as we would want to do for naked mole rats?
Yeah, we'll probably set up a special REMOVE_CASTES creature variation that will strip out any caste declarations and caste-specific tags. That should be clean enough. That'll go on some kind of "Utility Variations" wiki page, along with any others we end up using (REMOVE_VERMIN, REMOVE_BIOMES, etc).
Though unrelated to these templates, I need to say this: there are some tags, like [MUNDANE], [PET], [PETVALUE], [VERMIN], [PREFSTRING], [CREATURE_TILE], [COLOR], [GOOD]/[EVIL]/etc., and [WAGON_PULLER], that don't have obvious right or wrong answers. Before we start churning out raws, there must be some system in place that can standardize the use of such tags so we are consistent.
I think everything on the list is MUNDANE, and none of them can be considered GOOD or EVIL. Basically all real-world animals in vanilla are considered PET (except for some of the crocodiles, strangely), so I guess we can conclude that Dwarves are capable of taming most anything without assistance.
Yeah, all MUNDANE with no GOOD or EVIL is my instinct too.
As for PET, all the mundane terrestrial (and amphibious) creatures seem to have the tag in vanilla, but I don't think any aquatic ones do. That seems like a decent rule for us. PETVALUE... I have no idea. I'd be happy to just stick something vaguely reasonable in the templates and ignore individual species for the most part.
For WAGON_PULLER, PACK_ANIMAL, etc., I'd go with historical precedent.
For VERMIN stuff... like I said before, we can establish a rough size cutoff and make exceptions as needed. It won't make sense to establish that cutoff (or guidelines for exceptions) until we've seen how vermin behave in the next version.
Some may certainly be [SAVAGE] though.
Don't think so. I couldn't find any SAVAGE real-life creatures in vanilla.
We should find out if The Toady One intends to keep the [PET] tokens as they are in vanilla. It may not always be the case that dwarves can take bears and alligators and turn them into creatures safe to be around. The future critter genetics might complicate this, especially if individual animals have somewhat distinct personalities.
I think it's safe to say that PET and other similar tags will be replaced by more specific stuff later on, but they're what we've got for now (and the next several versions AFAIK) so we'll use them.
I think the PREFSTRINGS are something that people can just go ahead and contribute to immediately, although ones that are too "knowing" should be used sparingly.
Yeah, prefstrings are kind of troubling. They're fluff, but they have a disproportionate impact on the game's flavor. Also they don't work well when you have lots of similar creatures. We can put the generic ones in templates (e.g. "rough skin" for sharks) and others on specific creatures, I guess.
