Tecmo Koei made a fortune with video games based on The Romance of the Three Kingdoms. Sega has the profitable Sangokushi Taisen arcade game and Marvelous AQL hopes to capitalize on this epic with Kaio: King of Pirates too.
The latest company with a Romance of the Three Kingdoms project is Square Enix who are teasing Sangokushi Rumble with this website. The game will be revealed in less than 12 hours so it’s probably a social game for either mobile phones or browsers.
Why so man companies are making games based on the same tale? Well, The Romance of the Three Kingdoms is an epic most people are familiar with in Japan and all over Asia. It’s ubiquitous kind of like fairy tales in the West.
