幻想郷大激突 : Touhou Impact — Steam game overview

Stored observation / content update: 2026-10-25T19:41:51.000Z

幻想郷大激突 : Touhou Impact is an unofficial Touhou Project fan game. Youkai have appeared—far too many of them. This is clearly an incident, but don't worry. In Gensokyo, the answer is simple: beat them all up first, then find the culprit later.

Upcoming game. Player and sales observations may not yet exist.

Revenue is modelled, not confirmed sales. See the methodology and uncertainty range.
