I am using the LH in there for Persia, which I view as Achaemenid, Sassandid, Safavid and Qajar, which is roughly native rule (Yes, I am adding Iran, but I will explain later), although each of those periods is different. Adding the Sassanids, would cause me to rename the "Persian Civ" to "Achaemenid Civ" and would force me to add the Safavid and Qajars, keeping in mind that no one has made the latter two, and missing art is the biggest roadblock, not to mention the number of redundant city names. I would be happy to add Safavid and Qajar LHs to Persia, the issue is that either satisfactory art does not exist, in use for the ability to add another civ, or I am keeping in reserve to add another civ; the latter excuse only having an impact during the early-middle part of this project.
Keep in mind that I am adding the Seleukids, Baktrians, Parthians, Scythians, and Timurids, which should represent parts of Persia during other points in history. Iran is being added mainly for cosmetic reasons, namely for city names. It would bother me that Khomeini would found Persepolis rather than Tehran. Persia, is going to have to be one of the "clunky" civs included such as India, Polynesia, Anishnaabek, Holy Roman Empire, Dinnehih, Arabia, etc. for reasons of programming.
There are plenty of medieval Europe LHs I have yet to use, so sure. Should be fun since I am also adding Harald Hardrada for the Vikings (Hopefully there will be no complaints about redundancy since there will be Vikings, Denmark, Sweden, and Norway).
Although I am using the LH art provided in there for Murad Bey of Egypt, there are still enough steppe and middle eastern LHs I am not using, which means adding them is no problem. I am surprised Civ Gold did not have them in it since there is an "Ottoman" Civ, compared to a "Turkish" Civ, Friaxis really through the door open for adding many different Turkish civs, yet they dropped the ball by having the Native American civ use only Sioux city names. Besides, they will be necessary if someone wants to convert the 1000AD scenario provided in BtS for AND.
Kind of a preemptive comment on the Mughals, they are kind of split between Timurids and Indians. Babur was included with the Timurids when I converted that module, and I like Akbar as an Indian leader since his lasting legacy was religious tolerance (just don't tell a Hindu Nationalist that
). I know it far from perfect, but it close enough, which is how I was able to convince myself on converting Mycaene, Minoa, and Troy. Now, the Indian-Subcontinent Civ I would like to see more is the Maratha Confederacy; again, I must plead lack of art.
With all that said, the Anglo-Saxons and Seljuks will be added to my To Do List after I finish with Norway (had to add it from scratch, really surprising since art exists, just never put together). Finishing Norway will help me de-clutter files. I would like to add that I want to added enough Civs and LHs for people to be comfortable making scenarios for different periods in history.
