I see your Czege and Beltrán in the map, etc. Nice. As a UK reader though I'd struggle with applying childhood memories to the US-ish layout of the place. Is there much to stop me using a map of my nearest city, say? (I mean, try finding a block structure at https://www.visitchichester.org/sites/default/files/CITY_CENTRE_MAP.pdf - but I could see the cards still working with the shapes afforded here.)
Not sure if I'm shuffling the different backs of the memory cards together - it looks like there's people, events, places to remember, right? I'm thinking you do, but that means you can't use the information of the different backs to affect what you pick up; in which case, why have different backs? So other players can see what sort of memories you might play? (This is an interested question, not a rhetorical way of saying don't do it.)
I like the character generation very much. Zombie World does a similar thing, but this works it in with the game's tone (which is nicely consistent).
You're very clear in instructions! particularly in the facilitator's notes.
I'm late to adding notes - hence brevity! hope it doesn't come across rude - and I see there's lots below you've already seen. Not going to repeat any of them, except I think I want to endorse the part about wanting to see something happen to the given map as well as the creation of the new sketch.
bravo, and thanks for sharing.
