pollute it.

Is it possible to generate enough pollution to degrade it, if I'm not playing Silicoids or a custom race that doesn't need food? I don't think I'd be able to get the population high enough with, say, Bulrathi. x.x

i think it has a base cleanup of around 40 (could be on large or huge, which makes it easier on smaller ones) and you should be able to get 5 people there without any problems. if i remember correctly, one production is 1.5 pollution, so 35/1.5 approx 22 production. 5 from buildings. so yes, as long as you dont have ultra poor it is definitely possible.

I did have the amusing and terrible thought of dumping a bunch of transports worth of population onto the planet for several turns worth of production even though they'd all die... essentially polluting the planet with the ashes of millions of... we'll say criminals.

It's an odd case of a random spawn around a brown star. What's the % chance that happens, anyway? I hadn't seen it happen yet in previous games, though I did just buy this during the recent Steam sale, so I haven't had many games of it yet.

sounds like you found that one at the start of the game. just leave it the way it is and have 5 people there as soon as you got the buildings for this

Yeah, it was in a system adjacent to my starting point.

I was curious about the % chance for brown stars to generate an uber planet, though, because I'd restarted using the same seed (I'd forgotten to save on Turn 1, and had wanted to scout a couple systems), and originally, that system had been a small desert, but on the restart (with the same settings and seed) it was a huge inferno.

If the % chance isn't terrible, I might restart a few times to see if it'll give me a nice planet I could settle. Nicer than a small desert in any case (except inferno, haha).

uhm.... when you restart a game with EXACTLY the same settings, you always will get the same galaxy.
the question is: what are those settings? from what i observed, it is not only what you can choose in the lobby as game settings. your race, even the perks for same race custom races, also change some things in the galaxy. however, i had a feeling the galaxy generation tries to troll you. i once had a galaxy with tons of gaia planets close to me, while i played lithovores. playing the same seed with a non-lithovore race changed the planets to lvl 2 biomes

I thought was the case, but here's what happened:

First load: Custom with 20 points picked, plus also the +200 and Omniscient (both temporary). Tried out some random seeds until I got one where I had a bit of breathing room. I'd looked around a little bit to make sure I wasn't surrounded by a quagmire of solely bad biomes. Good variety, so I noted the seed.

Second load: Same variables, except I switched the selection order of the 8 opponents since there had been a spot with two starting locations which were pretty close to each other and I thought it'd be best if those were both "friendship-inclined" civs so they would probably avoid reducing the opponents to 7 really early on. Everything around my starting area looked the same.

Third load: Same variables, except I turned off the +200 and Omniscient. In two previous games I'd noted that didn't make any difference to the map generation that I could determine. I started to send out my scouts to look for anomalies, realized I had forgotten to make note of where I wanted my first colony ship to go, and so I went to load from my turn 1 save once I'd figured it out, but... realized I hadn't made a turn 1 save.

Fourth load: Since the same variables should produce the same result, I just restarted, having noted where I wanted my first colony ship to go. But as my scout went to one of the adjacent systems with a brown star to look for anomalies, instead of the small desert planet I'd noted being there before (my custom race has forest biome, so it being desert was worth remembering), it was a huge inferno planet.

Note: Subsequent loads (I've done about 9-10 now, out of curiosity) have all resulted in a small desert planet.

With standard 5X, you can "cool" volcanic back to barren, but Inferno planets (actually any Uber biome) have no options other than destroying or polluting. There is a nice Mod called Planetary Core Engineering (by Steel) that will give you ability to terraform planets to Volcanic or from Volcanic/Inferno back to barren.

I personally dislike not being able to transform Uber planets, as any civilization that has developed the knowledge to terraform biomes for the better, would certainly also have developed the technology (probably first, as a weapon) to terraform biomes for the "worse". I added to Steel's concept and have the TechApp "Uber De-Evolution" that allows you to terraform any non-Inferno Uber biome (except Orion) back to a Terran biome. This provides you options with conquered Uber planets to not have to leave them as-is if another biome would be your preference. Probably not needed if you prefer to conquer by Infantry, but i prefer to bomb the planets empty.

I have not posted my alterations, as it was built off an existing Mod and have not seen from comments on the boards that there was much desire for it, but could do so if wanted.

The ai most likely doesnt understand that project is bad for them, which could result in an endless terraforming loop.

@Sensei, agreed it's possible, my games have not demonstrated that, likely from my observations that the AI ignores it completely, again likely unless I modify some of the AI tech files. However, it is no worse than the destruction or pollution "tricks" neither of which have I ever seen deployed by the AI. Thus, my tech provides the same outcome in a more logical way. It is a choice between Gaia and mine, and it seems AI always chooses Gaia based on techs they have versus me. For me, the choice of Uber / Anti-Uber is a needed one as Gaia is not-needed with any Uber biome as a perk. I know 5X does not "approve" of techs not used by the AI, but it has plenty of other advantages at high difficulty levels. Thanks for your thoughts.

Oh, right. It is also possible that the ai realizes it is bad and doesnt think far enough to see the advantage. So it wont use this.
This tech gives an advantage to human players. Of course, this still is an argument, if you do this with pullution, but at least human players have to waste some potential

The AI should build any uber transformation they're given. I did tell those races with uber to prefer choosing volcanic cooling over gaia transformation, so in most cases they hopefully shouldn't end up choosing between their uber and a gaia.

I guess in most cases they are spying and sooner or later they will get it.
