The Apocalypse World first session worksheet has eight Fundamental Scarcities marked on it. To wit:
Hunger
Thirst
Ignorance
Fear
Decay
Despair
Envy
Ambition
The book doesn’t explain what the point of this theme list is, but I can see how the first six, at least, a clear themes of the game. Post-apocalyptic settings get a lot of their emotional power from those things.
There are other things not on the list that could motivate threats – bad blood, tradition, war (on a larger scale), lust… but they’re not there. That implies a selectivity – things not on that list are not so important. They don’t drive towards the themes that the game is about.
So… with that in mind, does anyone have any good ideas for how we might adapt this idea to Dungeon World, or to any similar kitchen-sink fantasy game?
