Main Topic

Tonight, we bring you PART TWO of March Madness, which is legally and ontologically distinct from any kind of sporting event you may be aware of. What did we do in Part 1?

In Part 1, we talked about ways that mental health, illness and trauma can be used and misused in horror gaming, with some expert advice from our friend Perry Clark. Now that we’ve set a baseline on the role mental health and sanity in general can play in gaming, it’s time to get into the game mechanics!

And as we mentioned, we are joined today by the extra-fantastic Maverick Haenze, beloved friend of the show. Can you tell folks where they may know you from, and what expertise you’re bringing to the conversation?

So: Let’s dive in to our discussion. Where have mental health and sanity mechanics been, where are they now, and where might they be going in the glorious future? Bridgett, can you kick us off? Do you have a favorite sanity or sanity-adjacent mechanic right now?

{For reference or review, some notable games with sanity/madness/mental health mechanics:

Call of Cthulhu, 1981, seems to have introduced the Sanity mechanic

Experiencing horrors leads to a “bout of madness” and then, potentially, long-term effects such as phobias/manias

More recently – players/Keepers can select long-term effects, and writers like Mav are introducing custom bout of madness tables in line with the story

Unknown Armies – get hardened by violence/horror, at a cost

Stress mechanics

Delta Green’s Sanity; can burn connections to people (“bonds”) to cut down on stress; fight/flee/freeze as temp effects

Trail of Cthulhu/Fall of Delta Green splits up into two tracks, Stability and Sanity – Stability is more like stress/mundane effects

Alien has stress dice/panic rolls

Blades in the Dark – vices which burn off your stress points

Note that these systems all represent a particular narrative worldview about how to deal with your stress and trauma!

Madness (more operatic/literary, less representative of real-world issues)

Trail of Cthulhu’s Sanity – affected mostly by exposure to mythos/unnatural

Vampire’s humanity/hunger

Metafictional effects:

Fear Itself (secret instructions to GM/players)

Keeper tricks at the table (describing mundane humans as horrible monsters)}

Topics:

Favorite current mechanics

What supports realistic play? What is more fantastic/genre-leaning?

Things to be avoided (e.g. some people don’t like the old-school random sanity effects)

Things you recommend – what are effective, fun, supportive for Keepers/players?
