Hi Ala al din,

what Techno Mage has done is to write a new file that makes it possible to use the Mongols in Multiplayer. To make them available in SP they would need Provinces, a tech tree, etc.
That's not done yet. barocca and I are planning to do this for a long time and when we do it we want to do it properly. They are supposed to get the same functions as the vikings, being able to profit from tearing down buildings and plundering, etc.

The other clans Taira, Tokugawa and Minamoto are supposed to get their own campaign as they are from a different time-frame.

The problem with the names is that some clans don't have enough names yet and so some are used double. Imagawa and Tokugawa are closely related, though and therefore it's not that wrong that Tokugawa named characters appear for Imagawa.
