Taisei Project (泰西プロジェクト) is an open-source Touhou Project fangame. Its development was started in 2011 by Laochailan, under the tentative title "OpenTH". Akaricchi, another programmer, became involved with the project starting in 2012, and the game saw its full first release later that year.
After a five-year hiatus, development on Taisei resumed in 2017, during which the project received many more contributors. Since then, the story was rewritten and a full soundtrack was composed, and various other improvements have taken place.
The current build features two playable characters and six stages. A future release will include a third playable character and an Extra stage.
Another villain threatens to turn the land of dreams into a place of terror. The barrier is disrupted, and a strange tunnel opens on Youkai Mountain that leads to an unknown land. Gensokyo is thrown into chaos as humans and youkai alike flock to this rift, where they will discover both new forces and old forces that have changed beyond recognition.
Taisei Project features original music in the style of ZUN, composed by Tuck V.
The Japanese word taisei (泰西) literally means "the West" or "the Occident", in a similar vein to the Seihou Project. However, the two series are not related.
