Cracking effort. Has anyone plotted out the most efficient research route?

AM1, Logistics 1, Military 1, Steel, Electronics, AM2, Steel Furnaces, Military 2, Improved Poles 1, Logistics 2, Oil, Liquids Storage, Batteries, Lasers (+damage/speed 3-4), Plastics, Adv Electronics, AM3, Logistics 3, Speed/Productivity 1-5 + Rocket defense (+ requisite techs).

Where not mentioned I have forgotten the requisite techs but they should be quite obvious. Early lasers are important for efficient biter clearing efforts and are the only thing needed for it besides electricity and poles. Military is handy to get a grenade production started so you can efficiently clear forests if you have any. For the rest you need to ensure you produce 1080 Electronic Circuits, 190 Adv Circuits, 30 Processing Units and 590 units of petrol to produce 1 Level 3 Module/min. That is 1080 Iron + 2000 Copper a minute, or more if you want to be faster. Thats 34 Iron Miners and 62 Copper Miners.

Crafting Speed required for the production of items needed for 1 level 3 Module per minute: (total crafting speed is simply the sum of the crafting speed of every assembler that produces a specific item)

Copper Wire: 16.67 (13.3 AM3)
Electronic Circuits: 9.0 (7.2 AM3)
Advanced Circuits: 25.33 (20.264 AM3)
Processing Units: 7.5 (6 AM3)
Plastic: 3.17 (3 Chemical Plants)
Sulfuric Acid: 3 Chemical plants from petrol to acid, needs 0.125/s petrol
Petrol: 6.45/s (~7.30 Oil/s with cracking, 4 Refineries, 1 heavy & 5 Light oil crackers (5.28 Crafting speed for the plastic, plus a negligible amount for sulfuric acid)

The number of assemblers, plants and refineries can be reduced with the use of speed modules, which can be recovered for the Rocket Defense.
I suggest using level 3 productivity modules (as soon as you've built them) with 2 adjacent speed beacons for the production of processing units, seeing as they are the best intermediate product to benefit from a productivity boost. Processing unit assemblers are the best productivity module candidates because they're very small and the greatly increased demand in electricity is still pretty minor compared to the total electricity of the whole system, which goes down because there need to be fewer because of the higher productivity. Only about 874 Electronic Circuits / Min are needed with 40% productivity on processing units, and that's with a recoverable investment of your first 12-16 level 3 productivity modules (in 4 AM3s) and 8 speed 3s to put in the beacons. An AM3 with 4 productivity modules and 2 speed 3 beacons produces at the same rate as an assembler with 2.31 Crafting Speed, hence the need for only 4 AM3s.

Great job calculating that! Next it should be good thing to see where the invisible hand lands when it comes to balancing production speed and time to start the production.

I did notice someone on reddit with a 5hr 20 minute speedrun. I'm planning out a route now so I can beat his time. He provides save file which is really helpful although the replay keeps desyncing because alpha.

Just spent some time checking out a tech tree path, I made it into a wsplit file if anyone wants to have a go.

Get wsplit http://www.mediafire.com/download/x6e6g ... _1.5.2.zip

At the bottom of the text file are icons for each split, they are found in your game directory, mine is on my "g" drive, you will have to change that to get them to display properly.

Ive not had a chance to play this through, while i did check for conflicts( prerequisites) it may not be right. Feedback is most welcome.

Apparently, someone now completed the game in less than 6 hours. Barely.

Yep, I certainly did

9hrs is pretty damn impressive alot of my games im still playing with trains and messing with laser turrets at 10hrs

Nice work.

Thanks
