Opposing stat pairs and shifting numbers?
« on: April 12, 2016, 04:20:14 PM »
A few RPGs have used opposing stat pairs before. Cthulhu with Sanity and Mythos, a gain for one is a loss for the other. Or the Shock version being something like Love / Hate in a pair.

And lots of games have shifting stats. WOD with its temporary and permanent Willpower, Glamour, Banality, etc which are mostly treated like resources, but sometimes also rolled. The recent Masks PBTA game has made shifting stats one of the center pieces of its design.

But I'm curious if any games, especially PBTA games have combined the two. Specifically an opposing pair of stats that shift based on play.

For example, if you were to do a PBTA back for Changeling the Dreaming, an obvious opposing pair would be Banality vs Glamour. Some moves would use Banality, other moves Glamour. But you can't have a high stat in both. Say a range of 3-0-3. Where a +3 to one would be a -3 to be other. During play and by making certain moves (or failing certain moves) you can shift that bonus one step at a time in either direction, but capped at +3. A score of zero would be balanced.

So...

Banality <-> Glamour
+3 +2 +1 0 +1 +2 +3

You start with a +2 in Glamour which is functionally equivalent to a -2 in Banality. So Glamour moves are easier, but Banality moves are harder. You roll a 6- on a Glamour move and your stat could shift down (Banality goes up), conversely when you succeed on a Glamour move your Glamour could shift up (Banality goes down). The reverse is also true. Banality makes you resistant to magic, Glamour helps you use magic. So their both desirable, though possibly not the greatest example.

My initial thought was 3-4 of these pairs as the stats for a hack. Possibly a Changeling game, but not necessarily. I think it could generally work in a lot of ways.

Is this something that's been done before? If so, by whom? If not, does that sound like it would be an interesting mechanic at the table?

Greg Stolze's "A Dirty World" (which despite the similarity in name is not a "Powered by the Apocalypse" game) uses opposed stats like this. What's interesting is that the stats are also used for the system's "damage," so when you're "attacking" a person, you're usually sliding points from one stat to another (e.g. bribing someone is pulling points from their Purity to their Corruption). The system is meant for Film Noir games and fits that flavor very well, but I'm sure that with the right choice of opposing stats it could be used for all sorts of stuff.

Either way, it's worth checking out.

My project, for now named "Mythopoeia", uses opposing pairs of stats that shift based on play. There are also stats that do not change. The dice mechanic is different than the standard PbtA system however. There should be a link to the current draft in my forum signature at the bottom of this post.

A forum thread on the project is here: http://apocalypse-world.com/forums/index.php?topic=7494.0
The first post of the thread is somewhat outdated though in its description of the rules.

Say a range of 3-0-3. Where a +3 to one would be a -3 to be other. During play and by making certain moves (or failing certain moves) you can shift that bonus one step at a time in either direction, but capped at +3. A score of zero would be balanced.

I used a range of 4-0 to 0-4 where a score of 2-2 would be balanced.
