Expedition: general discussions.

Nah. That's a tired trope that was stale a thousand years ago, Tivtrop.

It's a classic, not a stale trope. You just don't understand.

Bloodthirsty hellish creatures invading the mortal world, ooh, how scary, ooh, a deal for a soul, watch out not to commit adultery or steal.

Demons are rarely portrayed as frightening, so I don't understand what the words about fear are for. The only things that come to mind are some cheap horror movies or some pseudo-horror RPGs, like Mythos and Inquisitor (neither of which can boast quality). But the point is that attempts to scare often fail, both in movies and in games. And from an aesthetic or societal point of view, demons are sometimes well-realized, although not always originally.
