Current build order is approximately
1- Hab
2- Enclave
3- Reactor
4- Entertainment complex
5- Reactor or Factory
6- Reactor or Factory
7- Hab #3
8- Reactor block?
9- Entertainment complex?
10- Lab/barracks/Network Center
11- Lab/barracks/Network Center
12- Entertainment Block?
13- Lab/barracks/Network Center
Entertainment complexes are tricky because they cost 20 culture, and the very important Hab costs 25 culture. So we want to build the Entertainment complex whenever we can, but it's hard to build it right after a Hab, and it's stupid to build it right before a Hab, because then we can't build anything for a turn or two while we save up for that Hab.
Wow I need to use fewer commas.
I'm thinking we build a lab 10th if we can afford it, but it'll probably have to wait until 11th (just finished reactor block?) meaning Barracks 10th, and Network center might have to wait until Hab 4 depending on our science influence, although we should have +12 science income by then so maybe not...
Anyways that's just a rough outlook, things will definitely change. Might get free buildings, might deal with a surplus or deficit of one type of resource, or maybe the voter base will demand a lab suddenly, reactor block be damned!
Edit: if you look at that as a build queue from Civ, our production is pretty sexy; 1-2 turns per building, closer to 1.
Edit 2: in case it wasn't obvious, the ? symbol means it might move around the queue a bit, while the X/Y means that we'd build one or the other, to be determined later. If an X/Y option is near a ? option, then it's subject to switching places with the ? option.
Edit 3: spot the invisitext!
