Let me explain:
Right now i'm making a game about Insurgents overthrowing the actual statu quo by defeating it, to distribute the Power they kept to themselves.
So, i have this premise, this bunch of cool mechanics, all nice and clean, but...
This is a game. This has to be about fiction, right?
So, i need to fill this game, from the start, with something that makes everyone get it. What is this world? What is this Authority? What is the Power in this case? Plus, the way the things are feeling in the setting are important too.
Then i'm faced with a important question: How much is too much?
Spark RPG does this by an extensive setting creation, with factions, NPCs, and lots of worldbuilding.
On the lower range of the spectrum you have Sorcerer, where you have a few questions in order to make sense of what are you playing.
The question here is: With this Premise, the creation of the Pillars that reinforce the Authority, the feel and look of Power and the basics of the world (Is it steampunk, is it futuristic...?) should be enough to make a character and play?
What is the minimum Color in order to create the shared imagined space? In other words, how much do we have to create in order to establish this shared consent about what is there, and what isnt?
