I agree with your assessment that it’s not nearly as character driven as other PbtA. That’s the main habit we had to break. Basically, we now go in and out of character focus a lot more. Rather than looking for that level to push things, we are at the family level until there’s a scene where character action is either very interesting and/or resolves something. Getting into character scenes is easy with all that’s going on from a thousand prompts; the trick is to pull back to family level right after.
It feels a bit like a chronological Microscope game. Set up an age. Create big events at the family level. Think about whether a character scene would be crucial or cool for that event. If yes, do it and return to the higher level. If no, go to next big event. When enough events have occurred, turn to the next age.
