Heh, whoops! I fixed the link. I apparently grabbed the wrong file, my bad for rushing.
I don't think you need to rebuild the whole thing. I dealt with the issues by being flexible with some definitions.
Edit: So I thought about it and part of the issue I ran into might just be that I played with a character with less need to stay in the city. It might be useful in character generation to have a prompt that asks why the character needs to stay. Maybe they live there, maybe they are looking for someone important to them when the attack starts, maybe they need something from the kaiju, maybe it's their job to report on or investigate the kaiju. That would have fixed my thought of "Well, I'm out of here!" The goal is to be evacuated, so my mind just locks into "How do I leave?"
It also makes the day to day transition go away, especially if there's a prompt at the end of each day that there's some progress toward their goal.
