Thank you very much for your feedback. We're not so concerned about replayability: thanks to the genre, every time you can recreate a different kind of apocalypse every time you play and, speaking about characters, we believe that more open is not always better, simply because blank pages are harder to fill. Identity is a vast sea and a player is not going to create all of their character by themselves, so not only being the only teenager will be very different from being the only greybeard or the only strong adult, although the character sheet is the same, but you're going to receive the other identities from the group.
We hope in playtesting to find out about the map: in the end, we decide to not have crossroads because we wanted to rely on signs alone... And because it would have been a lot of extra work :-P We like the idea of rules about creating a map by yourselves and we worked on Google maps, choosing places not so far to our home as backgrounds, so it would be fun to ask people to do the same.
