Opening Remarks
I’m playing with Debug off for now. As you can see from the screen shot, debug mode puts a lot of extraneous messages that are too distracting for me right now. Once I’m comfortable with my understanding of the mod I may turn it back on to keep an eye on the AI.
It makes sense to me to divide my remarks into the categories of game mechanics, game aesthetics, and historical elements. If you want me to organize my posts differently, let me know.
Game Mechanics
Item One: Unhappiness is a major problem. Abdera in particular has no choice but to have almost half its citizens entertaining the other half. Only one item can be built in Abdera that would directly ease the unhappiness, and to rush it would use up the entire treasury.
Item Two: The point I was trying to make about Ampitheater vs. Theater is that they have identical costs but very different levels of benefit: Theater only adds 1 culture; but ampitheater affects 2 content faces. I know from studying history of theater that the Theater was used by the Hellenes as a major propaganda tool as well as a cultural influence. I would recommend either reducing the theater cost or adjusting its effects.
Item Three: I like what you’re doing with the various temples. However, why would temples not add to culture?
Item Four:
That tech rate is impossible at the start because of the unhappiness issue. Even given a slower research rate I cannot research “Battle of Granacus”. I’ve got only one option: “Standing Military”. I can click over to the next era, but can’t select anything.
Item Five:
It would be really helpful to know what you have in mind for some of these special units - Alexander and the named companions for example.
Guessing that they were “armies” I loaded a couple up with Phalangites. I then proceeded to attack with them and see them slaughtered at the first blow. At first, because I was throwing them against Memnon’s Army, I shuddered but didn’t flinch, if you know what I mean. After a couple of restarts, I finally noticed that these units don’t behave like armies. The units inside them do not participate in or affect the outcome of combat. Are they “helicopters”? And why can only Phalangites be loaded into the various holder units?
You will eliminate a lot of wasted effort on our part if you let us know how you are expecting these and other special units to be used. At this point I’ve probably put half a dozen hours into play. And I don’t have a good grasp of the mechanics of your mod, let alone start thinking about strategies for success.
Item Six:
Speaking of Memnon’s Army, is it intentional to have multiple iterations of it wreaking havoc simultaneously?
Item Seven: Could you also give us a word or two about why Alexander is a separate civ from the Macedonians?
Game Aesthetics
Item One: Some of your nomenclature choices have crowded the InfoBox:

Doesn’t need an immediate fix; but may need rethinking long-term.
Item Two: Some of the civ color choices may need rethinking. With caps-lock on I was watching a naval battle between 2 slightly different shades of brown and had no idea who was fighting who. I also saw purple units running around that clearly weren’t mine.
Historical Notes
Item One: At a first glance I like the Indian cities. Where’d you find them?
Item Two: What’s up with the border guard glut?
Closing Remarks
To me the whole point of play-testing is to give you detailed, even nit-picky feedback. Hence my dry-cracker approach. What you do with it is up to you. You should also know that I’m truly having a good time and enjoying a lot of what I’m seeing.
