Just downloaded this mod yesterday and thought I would submit my first impressions. So far I've played a migration campaign as Bactria and a campaign as Carthage.
1. The scope of the map is daunting. It's also very beautiful and the accuracy is breathtaking. I consider myself highly knowledgeable when it comes to ancient geography and it's challenging to find a neighboring settlement (especially in mountainous/forest regions.) Never the less I'm well pleased by the beauty of the map. Something I do not like are the forts. I see their practicality but just looking at them all sends my stress level through the roof. If they were removed I would not complain.
2. Many factions are dispersed far and wide. In the case of the Gauls and Celts I understand as this makes sense with reality but to lump Baktria in with the Greek states is not really a reasonable approach. I understand why you did it but for someone who is an avid fan of Baktria (secure starting position with phalanx and elephants heck yes) this sucks the fun out of my campaign. Maybe I can learn to love it but a pure Baktria faction would be nice if it could be done
3. I love the concept of an expanded build tree. I am not a fan of military buildings increasing unrest in settlements. Farms and mines make absolute sense but ports and military buildings doing so seems to discourage building a military in a far flung empire (see point 2) but I would think having a military installation in my town would provide order. A port provides jobs and people seem to like those as well. Also, the sheer amount of temples is daunting to navigate. I see what you were trying to do but the number of religious buildings is a lot to take in. Combining them could be an option but I will say the attention to detail on this instance was breathtaking. I know that some temples in vanilla influence the personal development of a family member. For instance the temple of Dyonysis always seemed to make my generals alcoholics in the long run. Do temples and other buildings still have an effect of character development and if so could this be at the least hinted at in the building info card?
4. I like what you've done with the units. From what I've seen they make sense and are accurate. If you've got plans for limited elite (hero) units that would just make this even cooler.
5. Probably my favorite part of this mod aside from that stunning map are the unique buildings. They add a certain flavor to the campaign. I've seen this tried out in other mods and I think it adds a certain flare to each faction. I spend a lot of time deciding what factions I want to play then spend hours optimizing and building the perfect empire. Unique buildings always add a certain pride to your hard work of conquering your neighborhood and beyond.
I'm having a lot of fun playing so far and I've not had a single crash so yet (cross your fingers.) Well done and I look forward to more excellent work from you guys
