Please take a screenshot of the foreign policy window where it shows the AI's intelligence, or post a debug.err file which also shows it. Because this could be faulty AI or the game setting itself at the wrong level.

also relevent is how far through the game is this? obviously this is pretty bad at any time much further than 10 turns in, but would be interesting to know.

I have seen a similar sort of thing (not quite so extreme) late in the game against the iconians. difficulty was masochistic, and I did check the foreign policy to see their intelligence (having been bitten by that bit of strangeness before too). There were some strangely empty planets (looking at them by spying and after I had conquered them too).

I'll try to post a screenshot tomorrow, so we have a few more examples.

I've seen it too. for example with a minor race which I knew had built an economic capitol, but when I conquered it, it was filled with mostly research buildings, so I had to demolish them and rebuild it into a proper economy planet.

another was a class 5 world and each square had a bonus (class 5 worlds often have this), and every square had a farm on it, pfft.

so the AI still acts stupid as far as planetbuilding. and this is on normal difficulty

the AI still acts pretty smart sometimes with diplomacy, even though I had really good diplomacy vs the Korx when I wanted to get the planetary invasion tech, they said 'oh I don't think so, you're not gonna pull this bait and switch and use the tech against my planets?!.' or something similar even though I had no plans on invading them. I was able to pay the Korx to assist with the dang Arceans like the mercenaries they are I had to pay quite a sum, but it was enough to get them off my back eventually

I set the AI to bright, And find they have a class 35 planet with 2 factories, A starport and a farm on :/

Try dumping them lots of money and see if they utilize it to build up their planets. Without knowing if it's a glitch in intelligence, it could simply be a focus of spending on research, even if the planet is set to social production. Others may be spending all their money on crafting scout vessels and leaving the planets to rot.

Just a thought.

This is a planet the Terrans colonized at the beginning of the game, and they have never been at war, so they didn't sabotage themselves. It's June 2228. All AIs were set to Incredible (I checked) and they played like it, except for this. It looks like a bug because their social spending is very low, there's nothing in the build queue, but they're focusing on social production.

I found this to be true of 1.2 as well.

My AI opponents seem to have issues about building farms in 1.2. In some earlier builds, they overbuilt farms; in this one, I rarely see them. Many of their class 15+ planets remain stuck at 5 billion population for most of the game. Has anyone else seen this?

This as well.

I play on suicidal level, I think planetary building is WORSE then 1.11. At least before the AI would build something on the tiles, now they just leave them blank...


Oh yea 1 further point the AI's r not building any trade goods, galactic wonders etc... in my current game either...

yeah i noticed ever since 1.2 beta

Lets face facts, planetary building by the AI's is terrible and undermines everything the AI's do the longer the game goes on.

The AI's in the areas like colonization, research r excellent and combat is now good. But all this is undermined in the long run by its abysmal performance in developing its planets.

I'm playing on crippling or so difficulty and I am finding alot of this stuff also.

The AI moved its civilization capitol to a class 4 planet that had nothing else but factories, put a farm and a starport on a class 3 planet (which cant support more then 1.3 billion people in any case) and put a tech, econ and manufacturing capitol on the same planet. I also found that most AI planets are usualy stuck at 5 billion people for most of the game.

All the AI's clever micromanagement and economy bonuses just don't do it much good when it wastes half of its planets.

It does seem to be getting worse. I just played a suicidal game on a gigantic map against all AIs with fastest tech speed and just researched my way to a tech victory bcause all the AIs only used about a quarter of their planetary tiles.

Me too. I used to use tidal disruptors when invading cockroaches Torians just to get rid of all the damn farms. Not anymore. They only seem to build farms now if there's a farm bonus. I've seen it on every level up to Intelligent. I wouldn't know about higher levels.

They don't script what the AI does, to keep it flexible I guess. In this case, maybe they should make an exception. 1 farm minimum, if the planet's PQ8 or higher. 1 factory minimum, etc.
