is it even worth it to float? you start with so many workers now that you hit max saturation much earlier, where's Sholip, we need some numbers :D

here is my analysis on the viability of Gangnam Terran (or, floating to the gold base with the initial CC), actualized to Legacy of the Void.

The question was, is it still viable to open Gangnam Terran with the economy changes, which is an especially burning question now that Blizzard intends to change the natural base on Prion Terraces to gold.

Well, here is the answer in pdf format, or as pictures in the spoiler tag below. I recommend that you read the HotS version first, if you haven't already, as this analysis focuses on the differences between the two games, so understanding may be harder without knowing ideas behind the original analysis.

Thorough analysis:

TL;DR: It is still very viable to do the Gangnam Terran build in LotV, albeit a bit less powerful. You can still get a considerable advantage before the gold base runs out.
If you do it on Prion Terraces, where the natural is a gold base, the only thing you should be afraid is very early rushes specifically designed to punish this build; otherwise you should be safe and you can even reinvest your mineral surplus into more economy to play a stable midgame from an economic advantage.

Why is it called gangnam terran? Does Gangnam have some special meaning akin to gold?

Gangnam is a district of Seoul renowned for its wealth. Read more about Gangnam Terran here.

Great work! And so neatly presented too!

Also curious of the origin of "Gangnam Terran" although I've heard it for years

I think the joke is that gangnam is a rich part of seoul separated by a river, and by floating your command center to the gold on habitation station you are analogously crossing the river to the gold base which is the rich part of town, gangnam

This is right. Gangnam is a concentration of the wealthy in Korea (mostly), with Seoul already being known for its wealth compared to the other 7 metropolitan cities.

Good work. I could fear that besides having to defend rushes, the opponent can also take his gold base faster and perhaps with more workers. I am not sure floating to gold base will be a good idea realistically.

Does someone know how many rax(without add-ons) can a full saturated gold base support?

Btw, aside from the 12 workers, the other big difference with HoTS is the timing of the spawning pool.

In a hatch gaz pool build, lings are out at 2'20. ON prion, with the floating time of 27 seconds, your first rax ends between 1'55 and 2'00, so you'll prolly have time to wall off with a bunker and be safe.

In pool -> hatch build lings are out at 2'00(?) and maybe your could be in troubles

(first overlord scouts at 2'20 I think, so scouting shouldn't be an important factor...)

Well, assuming my income numbers are correct:
With 15 workers on the gold, you have about 18.8 minerals/s income.
A Marine costs 50 and builds in 18 s.
Every 10 Marine, you build a Supply depot (100 minerals). 10 Marines come out in 180/X seconds, where X is the number of Raxes.

So you are spending: X * 50 minerals / 18 s + 100 minerals / (180 s / X) = X * (50/18 + 100/180) minerals/s.
This should equal your income, so:

X = 18.8 / (50/18 + 100/180) = 5.64.

So in theory, you can support more than 5 but fewer than 6 Barracks, so you should build 6. (Or 7, if you macro poorly
