Touhou Project Mod: Open Gensokyo Map

Handcrafted Open-Source Map for Touhou Modders! Calling all Touhou Project modding enthusiasts! I’ve poured my heart into creating this map to give fellow creators a canvas to realize their visions. While I’ll keep maintaining it, my technical skills fall short for landmarks and unit models—any help from pros would be a godsend!

The country files are stored in their respective folders - just click to open them and you'll see the documents.

I am working on my Touhou mod.It could come about 1 year or more #################################################### This map took over half a year of on-and-off work. Most regions were hand-drawn in Photoshop, and while the heightmaps and terrain textures might not win beauty contests, some areas shine. With 1,000+ provinces (close to vanilla HOI4’s scale!), it’s fully landlocked—naval warfare is off the table for now, though a "gap navy" version might come later. My pride? The lore-friendly that scream "Gensokyo"!

Sharp-eyed folks might recognize parallels to ROA—that’s intentional! This started as a ROA submod to fix its... questionable map design. But as my ambitions grew, I scrapped ROA entirely and rebuilt everything. By fate, fellow disillusioned ROA fans and aspiring modders rallied around this project, breathing life into a new creative frontier.

This map’s potential transcends being a "ROA spin-off." I’m sharing it publicly to fuel the growth of Touhou mods in Hearts of Iron IV. Let’s make magic together!
