It’s also your job to make most of the moment-to-moment decisions about what’s legit and what’s not regarding the rules. Most often, you’re going to decide when something in the game deserves a roll, what type of action that is (overcome, attack, etc.) and how difficult that roll is. In conflicts, this can get a little more complicated, like determining if a situation aspect should force someone to make an overcome action, or deciding whether or not a player can justify a particular advantage they’re trying to create.
