A great exchange (though long) about how and when you can/should apply location aspects. (From the FATE mailing list.) The following is my nickle summation, though the whole dialogue is an excellent one.
- Compel a scene aspect when: It complicates the narrative in an interesting way.
- Apply difficulties due to the situation when: Players are already invested in the scene, or an obstacle affects all sides equally.
- Ignore mechanical penalties when: Failure doesn’t advance the plot interestingly. Rolling against a boring obstacle doesn’t do much for the story; move on to describing how it slowed/impeded their efforts but get on with the story.
Here’s the thread. Lenny is responding to a general question about scene aspects and difficulties:
As a player or GM, you can tag a scene aspect to give yourself a bonus or to compel for effect. On one level, that’s mainly about simplicity; SotC has a fair amount of crunch to it already if you use every rule in the book. So “penalties” are always positively facing; they’re bonuses for the person who’s going to roll against you or for the obstacle that you face. Ultimately, if there’s no resistance, then failure isn’t particularly interesting, and hence it doesn’t matter.
