The 17th and most recent main game in the series, Touhou Kikeijū: Wily Beast and Weakest Creature, launched on Steam in September 2019.
Game developer Phoenixx announced on Saturday that Touhou Luna Nights, the latest dōjin title in the Touhou Project franchise, will get a release on the Nintendo Switch this year.
Team Shanghai Alice released the first main game in the franchise, Touhou: Highly Responsive to Prayers, in 1995 on the PC-98 platform.
Since then, the series has spawned other main games, multiple spin-offs, and many fan-made derivative works based on characters and stories from the series.
