[Humabout]

I don't know about any games, but you might enjoy looking up some information on Shintou or perhaps some Taoist stuff. I could easily imagine secret Japanese Shintou cults working powerful spirit magic or Taoist cults redirecting the flow of qi through the lands.

[EDIT]
Perhaps the Clan of the Midnight Sun, among whose secret members include several prominant Nanjing investors, is having a series of hotels built near the Yellow River in order to redirect a prominant dragon line so it will merge with other lines in time for an important ritual casting in three years.

Meanwhile, the Yamaguchi Clan has nearly doubled the number of shimenawa in Izu and is dedicating a beautiful new shrine to the kami of the peninsula in order to gain their assistance in casting ill fortune on the Midnight Sun's construction projects, since the new dragon lines will almost certainly cause an increase in earthquake activity in Honshuu.
