I played Greece up to turn 136. I encountered NO BUGS! I did not have Scrambles' city build problem with unbuildable Myth units showing up.
Yes, I'm pretty sure that was a cache issue.
Comments: started on an island alone with only two luxury types. I went LIBERTY but this turned out to be useless as I was in minus happiness with two cities despite my two luxuries and the +happiness liberty policy and three priest specialists. It seems to me that liberty is not a viable choice in this mod for the ancient era - is this correct?
It's not that Liberty is not supposed to be a viable choice. It just means that my Happiness balance is off.
Here's the problem. In the Mythology mod right now, I reduce your Happiness in three ways:
> A flat -3 Happiness
> 1 less Happiness per luxury
> Population adds 1.5 unhappiness per pop instead of 1.2 (assuming you're also using the Empires mod).
This is overkill. I KNOW it's overkill; I'm just trying to figure out which of those three needs to be toned down first. If I remove the -3 then you'll be better in the short term but will have the same long-term issues. If I remove the -1 per luxury then it makes luxury resource tiles even more important than they are now (since many Foci boost yields for various resources). If I remove the x1.25 for population then you'll do much better in the long term but still have short-term issues.
So depending on your feedback, this'll tell me which one needs to be tweaked most. If you're fine for the first 50 turns or so but then start having massive unhappiness when you get to having two or three decent-sized cities, then the x1.25 is most to blame. If you're having the issues right away but they don't get much worse later on, then the -3 needs to be removed.
Now, the intention is that you'd use Priest specialists to make up the difference. Each Priest adds +1 Happiness (and 1 food, and 3/6/9 Favor), so if you find yourself just a little below 0 then you should be slotting these (which'd have the added bonus of more Favor). If you find that you just can't fill Priest slots without starvation or having your build queues stall to unreasonable times, then that tells me I need to tweak the yields of Priests, but you're supposed to want to use these fairly often to offset the unhappiness. (The logic here is that if Priests are a necessary thing to use, then the AI will use them. If that extra happiness wasn't necessary, then the AI would never bother, and that'd kill its Favor generation.)
Or, just pick the Beauty focus when you have a chance; it's sort of the Piety of foci, the happiness-booster you should be taking if you can't seem to stay above 0. At the moment, no other Focus adds Happiness, but the solution might be to change that. Maybe Travel buildings should add +1 happiness to cities that are connected to your capital, or maybe Art buildings should add a little happiness instead of being only about Culture, or maybe Justice should give a bonus when Heroes are nearby.
Now, I'd thought of other ways to deal with this. Have every Church or Basilica add +1 Happiness, regardless of Focus. (The Basilicae, especially, can get this; I removed their Priest slots, because it's kind of a waste to generate Favor in a building that's already maxed out, but I can easily pretend that they have a permanently slotted Priest and just give every one that +1.)
Or, have every Basilica act like a toned-down Forbidden Palace, reducing the population unhappiness slightly. Since you'll only ever have two, and they'll be spaced out (with one coming in the early Medieval and the other in the late Medieval), it wouldn't get out of control.
I had very serious gold issues, which is why I abandoned the game. Both cities on max gold focus and only one military unit (deleted the others) and still in minus gold. Is this intentional?
No, it's not, but I'd need some exact numbers to fix it. The Mythology policy (which you're given automatically) includes an inherent penalty to gold output, and that might just need to be removed or toned down, but I'd need some solid numbers to be sure. Right now it's a flat -25%, but I could either reduce that to -10%ish, or add some semi-offsetting bonus in the base policy (like an extra +5% for gold-producing buildings).
Shifting a city to gold-production focus is never supposed to be required. You're supposed to be able to maintain a decent standing army with all cities on Default without going negative; if that's not happening, then I need to tweak the penalties. (This is the exact sort of thing I needed outside feedback for.)
Simple question: what Foci did you have? Primary, Secondary, and any Minors you'd added? Things like Wealth are obviously going to help with gold output, but quite a few other Foci boost gold for certain resources. Basically, I added a half-dozen or so separate penalties, and your choice of gods are supposed to basically neutralize two or three of those penalties. So if you'd only taken War, Fire, Death, Darkness, etc. then your military would be doing just fine but you'd have problems in quite a few other areas, while someone who took Fertility, Water, Wealth, and Beauty might have none of the problems you'd described but would have a pretty weak military.
Otherwise, it all seems to work. One minor bug was that one of my units had a flag promotion promising I could paradrop it anywhere in the world (but I couldn't, unfortunately) despite not taking this deity option.
Hmm, that's the Orbital Drop thing mentioned previously, and it's definitely a bug. Was that the ONLY promotion the unit had? (If you're hitting the promotion cap, you'd see all of your units get extra promotions that they shouldn't.)
--------------------------
Also, one other question: were the Events popping up? (I've only got one event in there at the moment, but in the end there'll be a couple dozen.) These are supposed to be one of the main ways of offsetting the penalties of the Mythological Age; your cities might be short on gold, but an event might offer you a free 100 gold. Later events I'm planning to add might give you a free Gems deposit near your capital, or give you a free Hero, or add a permanent +1 Happiness to your empire. These sorts of things would go a long ways in offsetting the deficits you're seeing.
