Koei has managed the perhaps unprecedented feat of accidentally publishing the wrong game, after it attempted to release a PSP version of Romance of the Three Kingdoms VIII, only to mistakenly place Romance of the Three Kingdoms VII on all the discs.

The title, released on the 12th as part of their “Teiban” classics series, included the wrong game on the UMD but was otherwise correctly marketed as VIII.

Koei have published a suitably formulaic apology, expressing their deep regret for the “great inconvenience” they have caused customers who were expecting the game on the package.

They also promise to replace the game with the right version, and have cancelled all sales of the present special edition whilst they sort out the mess and doubtless assign a few employees to cleaning toilets.

How exactly the mistake came to pass and how it was possible for them not to have picked up on it until the game was on sale has been the subject of much speculation, although it might always be possible games in the series are so similar they did check but didn’t notice…
