B/X Known World
Monster of the Week is the best in class for this style of game by a long, long way. It's designed from the ground up to be exactly this style of game. It's main influences are the shows you list. It has some of the best monster creation and scenario creation rules/advice you'll find just about anywhere. I can't recommend it highly enough.I'm likely going to be running a monster hunter campaign in the near future and I'm trying to capture the tone of the tv show Supernatural with a bit of X-Files-style investigation. So far I have narrowed my potential candidates list down to Monster of the Week (Evil Hat Productions) or potentially Hunter the Reckoning (Renegade Games Studios). I might just opt to go with my general-purpose horror RPG of choice, Shiver (Parable Games) if none of these would seem to do the trick well.
Which one of these games would capture this essence best?
To me, monster hunting and horror are not the same genre. It comes down to the power of the protagonists relative to the monsters. Completely different tone, vibe, and style.
Call of Cthulhu and Dread are fantastic horror games, but neither one will remotely feel like Supernatural or X-Files. The closest you might get with a more horror-style game is Delta Green. It's based on Call of Cthulhu but it leans far more into the government conspiracy and monster of the week tone of X-Files and shows like Fringe. But the body count of main characters will be dramatically higher than either Supernatural or X-Files.
