Sounds like a great idea, though I'd like to point out that the wiki says giant moon snails are about the size of llamas, not grizzly bears.
They're closer to grizzly bears than llamas:
Llama: 180,000 cm3
Grizzly bear: 200,000 cm3
Giant Moon Snail: 201,400 cm3
It's more bulk than height, so fat creatures end up seeming much larger than other creatures. You could (probably accurately) argue that grizzly bears are just fatter than llamas, but giant moon snails don't seem the "slender type" either. I go by numbers specifically to avoid thinking about body types.
The size numbers are off in any case: many creatures are almost identical in size. The
vast majority of giant creatures are between 201K and 203K, and most of their descriptions end up with "the size of a grizzly bear". Similarly, the
vast majority of animal people are around 35K. I just refer to them as "small" to avoid repetition, which is consistent with the descriptions for other humanoids.
My preference was to delete the giant creature size comparisons entirely: these numbers are best kept in the RAWs where they belong. I was convinced to keep them, though. Perhaps some middle ground could be arranged to convey that most of these giant creatures are larger than a dwarf but far from the towering monstrosities you might imagine when you first see them: I'd need to rewrite most of the descriptions again, but it might be better than endless grizzly bear comparisons. If anyone has any ideas, please speak up.
Thanks for letting me know, in any case, and thank you for the compliment!
EDIT: would this work instead? It implies that 201K is somewhat larger than dwarves, but doesn't make it obvious that the sizes are almost all identical. I'm liking this approach, so I'll probably go ahead with it if I get no objections and I can't think of anything better. Thank you for getting me thinking about this, bloop_bleep!
