Which Mod Nations are Ready for Prime Time?

[Velusion]

As a way to make things more interesting I'm thinking of including some mod nations in the next MP game I host. I'm looking for a list of middle era mod nations that have been tested more than once, that are considered balanced.

Requirements:

1) The nation must be unique and not derivative of an existing dominions3 nation.
2) The nation must have been tested (played more than once in MP).
3) The nation shouldn't be *completely* derivative of another fantasy world. (I.E. I don't want to exactly play the shire hobbits from middle-earth but I wouldn't mind playing a unique halfling nation.)
4) Must be designed for (or easily adaptable to) the middle age.

I have very limited knowledge of the existing mod nations so I'm looking for suggestions. The cream of the crop!

Thanks!
