You need to build all the basic units, plus all the civilization Unique Units from the original release nations (no DLC). I'm sure the UUs are required as I popped mine on a Naresuan's Elephant.
It was a surprise to me, but the achievement logging has apparently been re-enabled at some point so you can check on your progress. Here's how (Hat tip to this CivFanatics forum post):
- Navigate to My Documents/My Games/Sid Meier's Civilization 5 (my path for Win 7)
- Open config.ini and change the LoggingEnabled line from 0 to 1
- Run the game and it will create a text file called "achievements_debug.log" in your Logs directory under that Civ 5 folder
Interesting note, the Spaceship parts are also tracked in this log, but I'm not sure if they're required or not for the achievement.
So there is no good answer to this question, or it would already appear in the larger build order questions on this site. Unlike the early game (which is well defined) mid to late game doesn't have an easy answer, and anyone who gives you a BO past 20 is a snake oil sales man.
Even in the Zerg question you linked the answer was: What ever feels best.
Let's look at some of the basic Protoss builds and how they progress:
4 Gate
Usually this build is very all-in, and you're banking on winning early. However, if you do enough economic damage with a 4 Gate, but don't win you can still be at an advantage. At this point if you pressure more you're going to end up against a higher tech opposing force and probably lose, so you can expand here and maybe add on a Robo or two more Gateways.
3 Gate
One of the great things people like to do with 3 Gate is provide pressure so that they can expand. This sets them up with a nice little force as they transition into the mid game. Once expanding there are some people who like to progress to 5 Gate + Robo, or 3 Gate + Double Robo, or even (recently) 3 Gate + Double Starport. There is even a nice 4 Gate + Robo to provide pressure so that Protoss can take a third expansion.
You probably notice a number of trends between these two builds, even though I picked two builds that could not be more different there were a number of important ideas:
- Your Production must be proportional to your Income. If you have less production than your income you need to have a plan for it (eg. setting up to expand). If you have more production than your income you need to be aggressive
- Don't over commit. When you're ahead, your number 1 priority should be to get more ahead (ie. expand)
- While you always need to tech (ie. Red Queen Hypothesis) teching takes time, so don't forget that in your calculations.
Now you'll notice that a lot of what's being discussed is Income vs Production and there are a couple tools you can use to help you out:
Remember: To get good at Starcraft you need to get good at Execution and Decision Making, not get good at following a road map.

Retask SCV's to mineral collection when they're done building
When the first barracks is finished start building marines in it (6-7 I think) When the second barracks is finished build more marines out of it (3-4)
