Here's an actual question, though. If i were to narrate a game with a couple friends who have no mistborn exposure and little gaming experience, how would you teach the rules? By just playing? Having them read it? Another way?
I think explaining the world is the most essential step, and it should be done right away. I recommend developing your own pitch for the setting and culture, but if you aren't comfortable with that or are pressed for time, reading the provided introduction aloud (MAG pp.21-22) is a decent fallback. Having a custom pitch is both more personal and allows you to steer the conversation to parts that you are comfortable and familiar with.
I explain the basic mechanics while walking them through the character creation ("The crew sets their own goals, so . . ." "Dice pools are rolled to get the highest pair . . ." "Traits are worth an extra die when . . ." "You are encouraged to specialize . . ." "Recovering spent Standings and lost Resiliences . . . " "Improving your character . . .").
Encourage players to experiment with character building, rather than worry about getting it right. Remind them of the allowance to edit traits for free in the first Long Breather. Take notes of what they do during the game and suggest alternate traits for the ones that were awkward or unused when the time comes. Basically, make the process "safe" to avoid getting too bogged down.
If you can, set up the first scene to include a challenge roll with Circumstances in their favor, to introduce all the pool-forming mechanics in live-action. Then, find an opportunity to get a Contest, to define the differences and reinforce the pool-forming twice more. After the players are feeling comfortable and the game has progressed, introduce a Conflict and explain the process step-by-step.
I like to give players access to the Appendix, since the summary can help them if they are the "learn by reading" sort, and it can make them more aware of their options. But I also think Hero's method of giving them options is great, particularly for the ones who don't want to look at the paperwork.
