The unofficial translation of Gensou Narratograph is now available to download! (PDF only or .rar file with bonus assets)
I know no one ever actually looks at tumblr blogs, but I've made a basic page to hopefully collect information and links in the future.
An unofficial tabletop RPG published by Kadokawa. While the game as a whole is by no means "canon", it includes a full transcript of a game session with ZUN as one of the players, plus new character quotes and location descriptions written by ZUN, so it's worth checking out just for that alone.
Narratograph is largely boardgame-based, played with a selection of 30 characters gathering clues on a map of Gensokyo to progress through objectives and resolve the incident/kerfuffle of the week. However, it is still an RPG, with every scene being roleplayed and the incident also having a proper story to it. Narratively the game leans towards the light and feel-good end of Touhou fanworks, though I suppose it's up to you what you do with it. The book includes two prewritten adventures as examples, one of which I've run for a group to test it out.
It has pretty digestible mechanics, and a very unique danmaku combat system. To help with the number of sheets, figurines, tokens etc. needed, I've made public the Tabletop Simulator mod that I use to run the game myself, together with character figurines. You can use the assets included with the game to try and make it work in some other virtual tabletop of your choice. Or of course, you can also just print everything and play it live, if you can get a group together.
The rules have some quirks, and I'll try to figure out the best way to post my own notes and suggested houserules. As things stand, though, despite having nothing to do with the game officially, after putting a lot of work into it, I'm also curious to hear anyone's thoughts or experiences running it!
