The Silver Rule
The corollary to the Golden Rule is as follows: Never let the rules get in the way of what makes narrative sense. If you or the players narrate something in the game and it makes sense to apply a certain rule outside of the normal circumstances where you would do so, go ahead and do it.
The most common example of this has to do with
consequences. The rules say that by default, a consequence is something a player chooses to take after getting hit by an attack in a conflict.
But say you’re in a scene where a player decides that, as part of trying to intimidate his way past someone, his PC is going to punch through a glass-top table with a bare fist.
Everyone likes the idea and thinks it’s cool, so no one’s interested in what happens if the PC fails the roll.
However, everyone agrees that it also makes sense that the PC would injure his hand in the process (which is part of what makes it intimidating).
It’s totally fine to assign a mild consequence of Glass in My Hand in that case, because it fits with the narration, even though there’s no conflict and nothing technically attacked the PC.
As with the Golden Rule,
make sure everyone’s on the same page before you do stuff like this.
