Thoughts on ghouls? Not just begging for posts, I think they're definitely a really interesting monster to look at in ttrpgs when you look into them. There's a few interpretations
>the oldest classic, ghuls, arabic demon-ogre-djinn things that actually aren't undead but just feed on corpses. They're also not turned from humans, but are their own unique supernatural creature.
>the Lovecraft ghoul, also not undead, but this kind of weird corpse-eating dog thing that seems to derive inspiration from the europeanized interpretation which lost its djinn connections to be more boogieman-adjacent. A bunch of stuff is available on the specificities and twists on Lovecraft ghouls but they're pretty coherent.
>The standard modern DND ghoul, a more cunning kind of zombie, hungers for carrion, can turn people into a ghoul, they lose their memories and become feral monsters and there's like 100 flavors of them. Obviously very combat oriented, you have mere common ghouls and then Double Ghouls and Special Ghouls and so on.
>The OSR ghoul, which is a trend that you can find in a lot of gaming blogs within that sphere, in which the ghoul is humanized and made more pitiable and tragic (or evil but in a human way). They're humans addicted to carrion and slowly degrading in the course of indulging their addiction, eventually becoming undead sometimes without even realizing it. Unlike modern DND ghouls, they're intelligent if addled by their desires unless they were locked in a tomb for centuries. You can negotiate with or trick them if you encountered them, and some new ghouls that haven't died yet might be lurking in the community as undertakers or charitable gentlemen who pay for funerals.
Personally I like the original ghul and the europeanized gothic iterations of it and the OSR ones the most. If I ever ran a game and didn't just play one I'd have a connection between the two. I've always wanted to play an OSR-type junkie ghoul PC sometime as well.
