San Guo Da Luan Dou: Zhan Guo

San Guo Da Luan Dou: Zhan Guo is an RPG based on the first game in Koei's Warriors Orochi series. Warriors Orochi is a hack 'n slash crossover that has historical characters from China's Three Kingdoms period meeting historical characters from Japan's Warring States period. San Guo Da Luan Dou: Zhan Guo isn't a true backport, because it's an entirely different genre, and it instead just uses characers from Warriors Orochi and elements of its story. However Nanjing still marketed the game as if it were a backport of Warriors Orochi.
