Tecmo Koei joined the hunting game ranks with Toukiden: The Age of Demons.  While it came out just last month, Toukiden was originally announced in 2012 before God Eater 2 and Freedom Wars. 

"In Japan, there is a large market for portables like Vita and PSP.  Within that, there are a lot of people into hunting games, as well.  Capcom has been releasing their titles on Nintendo 3DS," producer Hisashi Koinuma said to Siliconera. " Because of that, we thought there are a lot of Sony users who would like to see a hunting game and that’s why we came up with Toukiden." 

Like many of Koei’s titles, Toukiden: The Age of Demons has hints of history in it.  The Oni are from Japanese myths and players can attach the spirits of Japanese warriors to their weapons.  Koinuma explained that, "Koei is well known for are historical titles, especially games based on Japanese history.  That being one of our strengths we used that has a key theme for Toukiden: The Age of Demons."
