what is the most optimal order of research!

[Humorous]

im wondering what is the best order to research stuff.

There isn't, really. I like to focus on production researches, so the ones that help make things automatic. Automation 1 is the first, because it lets you make assemblers, but after that I take a bit of everything.

Red and green science are easy and cheap to make, so there isn't really any reason not to take all research taht uses those two while you focus on expanding your base and/or getting oil production working.

The researches I leave for last tend to be the military researches, and specifically the weapons I never use (grenades, missiles, shotguns, flame, combat robotics).

Major researches to aim for would be automation 1/2/3, logistics 1/2 (and 3 when you got oils done), smelting, adv. oil processing (to get rid of the excess light.heavy oil), lasers, modular armor parts, stack inserter/bonuses.

I like to go for trains as soon as possible. Oil is next (the modpack I usually play with doesn't spawn oil in the start location, so I get trains + fluid wagons first). Then it's very situation-specific. Go for better weapons if there are biter nests nearby, for example.

Really it's all dependent on your playstyle. I also like to get mining productivity early on to get the bonusses working sooner to pay for themselves quickly.

My personal goal is getting bots and laser turrets as fast as possible.

Then i go for power armor.
Then i research everything to expand more.
At last i go for uranium.
