To flesh this out a bit more, I'm thinking we should require each player character to have a clearly defined Goal, a driving motivation for them to engage with the story. The characters don't necessarily have to implement it in-story immediately (since it's not always appropriate), but it should eventually become a key driver of their character. Whatever that turns out to be, it will greatly affect the kinds of items and powers they'll pick up on their journeys.

So it loops back around to role selection: players will be needing defined roles connecting their characters to the story.

EDIT: Nah, this isn't a good idea. We should let them decide on their own goals. This is hard. ;_;
