That sounds really cool! I think zines provide an awesome format for getting knowledge out their in an easier to digest format :D
You should make that game zine though! I've been trying to orchestrate one myself but have gotten overwhelmed a lil bit (a bit more than I could chew). For now, it's one of my many world-building projects.
The idea of a fill-in over-time zine sounds interesting as well :o It'd be a nice memoir to reflect on and see what's changed. I always struggled to fill photobooks but scrapbools and zines feel a lot more fun yknow?
I hope your day is awesome!!
