I'm fairly late (6 years) into my test game. Here's a detailed report on all the races:
Terrans: Good. They built up a military, which was the only change I really made, since most of the unique Terran techs are various fleet modules the AI won't use anyway.
They're one of only two AIs to research Alliances, allowing me to finally get an ally after being Close to them (and two other races) for years. That's fairly normal, though, and normally I trade Alliances to all the AIs when I get it. This time I unwisely traded it from the first race to get it (the Yor, of all... people) and with Tech Brokering off couldn't give it away.
Altarians: Absolutely dominating the galaxy. They've researched a fair amount of their Xeno Mysticism techs and built the Dark Energy Lab. They also have many of their post-Xeno Ethics good techs. Most objectionable behavior so far has been researching every single extreme colonization tech even though extreme planets were set to "Occasional", causing them to fall behind in other areas.
Arceans: Not so good. They're pretty much a has-been now and are losing a war with the Altarians. They also took losses to the Thalans and Drath earlier. No Xeno Geology (or anything afterward), no Planetary Fortification, not even any Navigation Center techs (which they have normally). I'm prepared to assume it's more because they just haven't done well all game, though.
Yor: Looking fairly good. They had a big boost when the Korx surrendered to them. I tweaked some of the values to their manufacturing techs and they're coming along well. They have the most advanced weapons in the galaxy so far (Plasma - tech inflation strikes again). They took some damage earlier to the Altarians and a lot of ex-Korx pirates, but now they're on the rise.
Korx: Died out before I met them, so I don't know if they went for their trade techs or not. Because the war that wiped them out was a dogpile affair with 4 or 5 races, I was worried they never even built a military, but all the pirates seem to indicate they did.
Drath: Fairly strong. They're still evil, since I forgot to reset their alignment. They aren't researching the Xeno Mysticism branch, and are technologically behind. They also haven't bribed many wars. On the other hand they have a lot of planets and are doing okay.
Thalans: Looking good. They're into their various unique techs now, having grabbed some of the neutral techs after researching Xeno Ethics. They didn't go as crazy colonizing as they normally did.
Iconians: Results seem mixed. They're in a much better position then usual, thanks to the fact that they actively researched their manufacturing and economy techs. On the negative side, their weapon of choice is still Scatter Gun 2, despite being six years in, which worries me that there still might be some issue with weapons. They also are still ignoring the Organic Hull branch.
Minors: Results are a mixed bag:
The Paulos are doing well, with 4 colonies and a large military. They're at war with the Arceans and Thalans but are too far away from both for anything to happen. Hilariously, they built a Dark Energy Lab on their homeworld after one of those random events where they stole the Altarians' techs.
The Dark Yor have no military, but a fair number of colonies. For some reason they got Barren World Colonization very early - maybe the Yor traded it to them?
The Scottlingas colonized many (7-8) planets but never built a military. The Altarians conquered them.
The Jessuins also didn't build a military even though they did get Planetary Invasion. When I declared war on them, they still refused to build anything but transports (which they never even launched). I made peace when they had one planet left so as to dodge the diplomatic penalty for destroying them, and they're finally building warships now.
The Carinoids are dead, conquered by the Thalans.
I just met the Akilians. They're looking strong and aren't at war with anyone.
I still haven't met the Lentzlandians or Snathi. I've had several reports of powerful races extorting the Lentzlandians, but I've heard little from the Snathi, except for a few wonders. Presumably they're stronger.
Incidentally, I am the Torians.
