There are tons of fantasy creatures out there. What are your favorites, and why? Are there any cool, barely known monsters you wished showed up more often in games and literature?
For me, my number one favorite is harpies. I just love the idea of bird-winged people, which are far more fantastical than people with pointy ears (elves) or short dudes (dwarves), but there seriously isn't enough harpy stuff out there... so I add harpies into almost everything I do.
I've also been researching Inuit mythical beasts, and I really think they're cool ideas for a game. are awesome - super-fast, man-eating, dog-legged people are a sadly underused concept. Although they tend to be weaker and not as clever as humans. Oh well.
