Is one Ecumenopolis "enough"?

[Bankipriel]

So, I got the free First Leage Ecumenopolis in my current game, and it is awesome.

I haven't played nearly long enough in any games yet though, to know if one is enough for a moderately wide-play game. I'm coming up on my third AP choice, and I'm wondering if taking Arcologies is just overkill/unnecessary.

So, has any one played far enough with Ecumenopolises to know if supporting more than one is crazy? Should I spend the AP on something else? Thoughts?

Depends, it took long time to fully unlock a potential of an ecumonopolis, my opinion is after you fully built ecumonopolis with district then its time to built a new one. Because two ecumonopoloss at the same i think its not very effective for population growth, at least get one to fullfill first with growth and immigration.

I built ecumonopolis on fully populated planet and decade later it still can support lots of new pops, like super lots.

1 Ecumenopolis can support 150 to 250 specialist pops, so, 1 ecumenopolis per 1000 pops is good fit ratio.

About Fen Habanis, it is super Ecumenopolis, not only give u 25 size Ecumenopolis, but give you extra 20 slot due to "ruined city" feature, that means total 45 district slots.
With Fen Habanis, The 1st league is now on pare with Cybrex in "1st tier" precusor chains.

Does it do that in the new beta branch? In my save, Fen Habanis gave me 28 districts (25+Expansion+MoN), 20 of which were blocked by ruined arcologies that I first had to remove.

EDIT: To say something on topic: I found that one Ecumenopolis is absolutely enough, and I turned a size 16 planet into one. Then again my empire has barely exceeded 1100 POPs, so Kroo's formula may well hold true.

Maybe im wrong about districts numbers .

Two could be useful if you are going for that 1,000,000 fleet power, and building bunch of megastructures on top of it. But if you are going wideish anyway, I don't think you'll run in to any problems with just one.

 

[Kahldris]

Ya I was going to make alot of them in my first game but quickly realized more then 1 didnt make a whole lot of sense.

Yes, you are most definitely wrong about that one Fen Habanis has 25 districts, 20 of which needs to be unlocked through clearing blockers. In no case are those additional districts on top of the base number.

I don't feel like one is enough. In my current game I had 4 by the time I had 30 planets, although two of them are quite small in size (21, 20, 14, 11). It's in part because I am playing fanatic egalitarian so I can't resettle pops onto them, but even if I could I wouldn't have less of them, maybe one less.

I would say it depends on
- your total number of planets,
- if you fully restructure your other worlds into resource planets (with the occasional special resource building and research labs),
- if you plan on fighting a high level crisis etc.

But all in all my feeling is, that any planet, that is not suited as a resource world (I.e. you are forced to build more than a handful of city districts because of resource district restrictions) should become an ecumenopolis. The ecumenopolis districts are just so much better, that even if you should run into a mineral/food deficit in the long run, you can probably always just use the market and earn tons of money from a few sold alloys.

I hadn't thought of it that way, you can also have a high trade power on those things as well which can be alot of energy. Hmm something to consider.

1 Ecumenopolis can support 150 to 250 specialist pops, so, 1 ecumenopolis per 1000 pops is good fit ratio.

City Districts give 15 housing, not 10. And more assuming you stack housing requirement reductions...
Combining communal, fertile and byzantine bureaucracy let's you decrease housing needs by 30%. The Red option from the Alien Box event let's you decrease it by 5% more (for primary species). And if you have Caravaneers they sometimes give you a Bunk Beds deployment, increasing planetary housing by 10%.
They can also give you +2 extra districts - which appears to be unlimited. Mastery of Nature also adds 2.

That's between 589 (No Alien Box) and 634 pops before adding more districts (most I've gotten is +6...).
At this point, jobs are a bigger concern than housing. If you fill up everything with Commerce Megaplexes you'll have 165 (1 merchant, 10 clerks, times 15 slots) jobs +8 from a fully upgraded capital.
You get 5 clerks from urban districts, which is too little to cover the extra housing... So you build more foundry districts.
Entertainment districts are unnecessary with this many clerks, and trade power should give you enough Consumer Goods to break even.

With the above bonuses (assuming no Alien Box, but with Bunk Beds) Every foundry district will provide enough housing for... ~15.71 pops.
We get 10 from the capital, so we can substract that from the 173 jobs we get from buildings.
Divided by the 5.71 surplus housing we get from foundry districts that means we only need... ~28 foundry districts to cover all the housing needs. That's almost possible with Mastery of Nature alone, or with Caravaneer RNG.

Assuming we manage that, you end up with 840 alloys base production per ecumenopolis, before taking into account modifiers.
Safe to say, getting a 1,000 is easily doable, though you're going to need a lot of minerals for that...

EDIT: I forgot to add that the adaptability tradition tree (replaces diplomacy for Fanatic Purifier/Inwards Perfection) also reduces housing needs by 10%.

matter decompressor?

 

[Leylos]

As much as I'd like another one, I don't produce enough raw resources for all those specialist jobs.

 

[Slynx]

since I use ecumenopolises for a trade mostly...I prefer to have 1 food planet and 1 rare crystal generating planet\habitat to support it. also if you want to switch trade to something else you'll also need forge world too I guess.

 

[Aquilegia]

If you are individualist and go at least somewhat wide, going with more than 1 is useful, simply because then you'll have double (or more) the growth of artisan/metallurgist jobs and aren't forced to still build forges/civilian industries on other worlds. If you're not individualist you could resettle pops on the ecumenopolis and let consumer good/alloy supply keep up with demand more easily (and so only need to convert a new ecumenopolis when you actually need it and the first ecumenopolis is full).

That sounds sort of keeping with previous suggestions of around 1 Ecu. per 1000 population. I'd guess 60-120 on most planets, average 100, yeah? So 26 regular planets is approximately 2600 population, plust 250? 300? per Ecu.? Seems like your total pop should have been around 4000k once planets were full. Wast it? I'm just curious.

I'm a fair bit ahead of where I were when I made them but I think in my case it was more like one per 600-750 but one per 1000 is probably not a bad guideline either.

 

[Aleriez]

Actually in my current game I do build the districts one after a another and buy the pops from the slave market for 1k a pop

 

[EvilKnievel82]

I currently have 3 at 30+ planets but they are nowhere near full at around 2380. My experience is that about 1 in 10 planets can support less than half it's district size in resource districts. But I have mastery of nature, which means you can use the good resource worlds better and the bad ones tend to have an even worse fraction of resource districts to total district size.
