Compendium, If I may, the following are some cities i hope for which you will add Mithradates VI to as a possible ruler in the pull down menu under Ruling Authorities.
Even tho he is mainly considered king of the Pontic Kingdom, he consolidated much of Asia Minor in a bid to keep out Rome. In Numista (under my section, Ancient Greek) the individual cities are still listed somewhat independently and not part of the Pontic Kingdom during his reign. https://en.wikipedia.org/wiki/Mithridates_VI_Eupator
The list includes (but isn't limited to):
Amisos, Pontos
Sinope, Paphlagona
Pimolisa
Kabeira (Cabera)
Pharnakeia
Taulara
Dia (of Bithynia)
Amastris
Amaseia
Abonutheichos
Chabakta
Comana
Gaziura
Laodikeia
