So, I've seen a lot of people discussing about the one-planet strategy and its validity in 2.2, I wanted to try it out but going even further, with only one system and no megastructures. I started out with a fanatical pacifist/authoritarian, life-seeded empire and the objective of expanding as little as possible outside my home system, but unfortunatly I had hyperlanes going right into an hostile hive mind, so I had to take a couple of system to place fortresses in, as my homeworld starbase was dedicated completely to building ships.

The first years passed pretty smoothly, but also painfully slowly as all I had to do was upgrade buildings and waiting for pops to grow, I had to delete my fleet and use all my alloys to upgrade my fortresses in order to keep the hive mind at bay. I decided to take the synthetic ascension, despite the many bugs, in order to saving on food for when I'll turn my only planet into an ecumenopolis and already filled it with many robots. After finally managing to finish the ascension with the few research I had and starting the arcology project however, I realized commerce alone wasn't enough to sustain my economy, so with my energy credits dwindling and my resource at minimum I begun selling out my alloys. I've heard before that alloys where valuable, but I didn't expected to be so profitable on the long run, so once the ecumenopolis was finished I just spammed forge districts all over the place, turning it into my main source of income.

At the peak of the planet development I was buying 950 minerals and selling 520 alloys per month, I've brought so many minerals that their price skyrocketed and even surpassed the consumer goods one. On the other hand the price of alloys was so low, I had to sell my resources to artificially inflate it so that I could still make credits out of it.
20181231200208_1.jpg

With all the alloys I made I build a fleet and vassalized the Hive mind, at this point I was the strongest empire in the entire galaxy, with an economic power surpassing even an awakened empire. Unfortunatly this empire was in a federation and had an overall score higher than mine, so in order to win the game for once, I built a colossus and shielded all his world while they were busy fighting the Contingency.

Without the awakened empire I was about the win, except I then realized I had to beat the contingency to actually end the game. I kept dragging on a war of exaustion against its 100k fleet but in the end, once I reached around 2450, I begun to experience the infamous stuttering many players have reported (something I luckily never encountered before, apart from the usual intense late game lagging on a medium galaxy) and the game turn literally unplayable.

So, is the one planet strategy still viable? Well yes, but that's not what I learned from this, I may have been already said but alloys are really a gamebreaker, I've tried the same strategy with a normal empire and I was able to become a superpower in a couple of months once I've finished my ecumenopolis. I thought city planets where op due to the trade value, but now I realize they're just massive capitalist forge worlds. ( °-°)

I did a 2 planet strategy with a life-seeded fanatic purifier on grand admiral. Build a habitat or two, an ecumenopolis, a matter decompressor and dyson sphere. I'm pretty sure it mainly works because the AI seems to fall behind after 2300.

People talk about population growth being the most important thing, and I somewhat agree early on. However, as the have progresses, your most precious resource becomes building slots. Since you ostensibly focused on building population growth early on, pops/building becomes a metric one begins to seek out.

Ecumenopoloi are so powerful precisely because they are so slot efficient in the one thing you need for military applications. Furthermore, they don't require any rare resources, thus they allow one to completely build without thinking about it. I think the balance of the mega-projects need to be re-thought.

Awesome stuff, nonetheless.

I think the real achievement here is how you resisted the urge to snatch Fen Habbanis.

May I ask what difficulty you played on? I'm curious if it's a valid strategy against GA/non-scaling. Great work nevertheless!

I was on Admiral with scaling difficulty and 0.25 tech/traditions cost

That's crazy, tell me how you did this; I'd love to give my friends a scare in an MP.

Once the galactic market is founded, just spam alloys. Keep producing and selling alloys until you ran out of minerals and then start buying them.

Not sure if that's a good idea for multiplayer, the cheap alloys will result in other players buying it and making gigantic fleets from all the bought alloys so you're kind of financing the enemy at that point. Ofc AI doesn't know how to spend its resources so it doesn't matter with them.

That means you can sell less alloys for the same energy, so you have more for yourself too. Not sure if it's really that bad, I just think that this whole strategy will not fare well against any expansionist players because they'll outproduce you in most if not all areas as they can manage better than the AI.

Maybe try it with glavius mod

I'm not so sure, you're benefiting all players equally, so while your enemies will get cheaper alloys, so will *their* enemies as well.

Try direct trading with AI nations through diplomacy. The AI seems to give a 5 minerals : 1 alloy ratio fairly consistently. Though this might not work on lower difficulties, think it's primarily grand admiral where the AI has enough of a surplus that you can buy 500 minerals a month for 100 alloys a month.
