Small example: Urban Shadows has not only four core stats for what your character does, but also four stats for the Factions in play. And players have both personal and factional moves. It (probably) works great! And it’s 2x the basic mechanisms of other PbtA games.

OTOH SotI has a lot of moves due to the man/woman move split but you only need to concern yourself with your gender’s moves. 

The Factions thing is just one example! It popped to mind when you asked. 

I am the first to confess that this isn’t like…a rigorously constructed “position” I’m talking about. No positions, no defense, no stomach for a lengthy fight today.
