Great-I love this mod and the research that's gone into it. What amazes me is how many of the factions, including the Aeudi, say, have their own new art , units and transforming reforms. I've played Rome, Carthage, Aeudi, Ptolemic Egypt, and found interesting stuff in every case. Haven't tried more 'exotic' groups like the Bactrians so don't know if even they have been given the same loving treatment.
I'll try 2.3 soon.
I miss only the cheesy Wonder films, but I can see why they are not in keeping with the tone of the mod.
While we're unfinished, it's a different sort of unfinished as to having factions without complete UI and such. It's more that lots of rosters are incomplete (especially regional units, rather than core factional ones) and we haven't scripted all the events and other gameplay features that will eventually be present. A lot of progress has been made between 2.2b and 2.3 on that front, though. Especially in the traits area, where they're now working much better, as a result of dealing with a huge bug with AntiTraits. Though that job is nowhere near finished, it's massive.
Baktria, as a Hellenistic faction, has the Greek core of it's units done already, and most of the Eastern/Iranian roster is complete as well. More recently, they've had the three "Indo-Greek" (in reality they're mostly and Hellenising Iranians) units added to the region, though they're still missing their elite cavalry. Their tributary events and independence reform are in, though, and they have a host of "missions" which give useful rewards like colonists.
Wonders are back, though no film, just a popup when you first find them.
