1. Frictionless Clothing and Ultra Spices are both unlocked by Xeno Cultural Trends. Ultra Spices used to be unlocked by Extreme Entertainment. It should be moved back where it belongs or at least moved somewhere else, 2 TG unlocked by same tech and giving almost same bonus is looking bad.
2. Hyperion Shipyard - briefdescription says it increases military production, but description mentions only quality.
3. Fertility Acceleration unlocks Aphrodisiac - which doesn't make much sense for Yor to have it. I suggest cutting out this tech completely from their tech tree - they won't miss it that much.
4. Empathic Tactical Center - both briefdescription and description still mentions weapons instead of defenses.
I'm running games to test how AIs fare against each other on Large maps with fast tech speed, painful, all planets/habitable/stars abundant, scattered, extreme occasional, rare anomalies, no tech trade/stealing, no mega events. First 5 games show problems with balance of some races.
This is still work in progress, I'm giving points for each AI according to it's performance, giving highest scores for research and economy, as in my opinion those are most important statistics and it's easiest to determine who is the greatest badass around. If AI is in a position I would not want to start the game (far away stars, being stuck in between other civs, starting in a corner) I give it +1 point. If it has great starting position (isolated with stars around it), I subtract 1 point.
Thalans are way ahead of everyone else in research and income. In all games they have twice as much research/economy then 2nd best civ. Their Influence is so scary, in game 3 they covered Korx completely in pink shroud. Honestly, something needs to be done about them.
Terran is doing fine. Just an average civ (average among strong civs)
Torians are ahead at the start of the game, but lose their steam towards the mid game and fall back to average. In other words strong, but still balanced.
Korx are doing bad, once or twice had good positions, but it never done them any good. They do get all the important techs, problem is they just aren't that good at colonizing.
Iconians are doing good all things considering, twice they started in the center sandwiched between other civs. Twice they started in good positions, and were at the middle of the rankings. They start with very strong research in the begining, but their economy crashes frequently starting from 50-60th turn, and doesn't stabilize until turn 80-110. I've seen it many times on Medium maps, but I do not know what causes this. You can see what I'm taking about by looking at manufacturing or research graphs, their line goes up and down all the time. All I can say, if their economy doesn't crash, their research can be equal to Thalans. In other words, if their economy is somehow improved, they will need to be nerfed, as their research can start growing exponentially and I've seen it twice on Medium map. Trust me, it's scary ^^
Yor if lands a good spot and colonizes on par with other races is also at the top (not including Thalan) in statistics. If they start close to influence of others and are cut off from the center or some stars that only they can grab, they suck like Korx. Most of the time I ctrl+n for them to have at least a fighting chance, so maybe unintentionally I rolled few maps in their favor. All in all, they are doing fine.
I was going to include Krynn instead of Korx, but I changed my mind as I didn't want all the good civs to gang up on lone evil Yor. Korx weren't happy with this choice, scrapping the bottom in every game.
Torian, Terran and Yor seem to be equally strong. Iconian underperformed because of their economy, but I've seen enough from them to know they have same potential as Thalans if they manage their spending well. Korx is not ready to fight alongside big boys, and Thalan is the man of the house who most likely will need to be nerfed in some way.
