Let me just respond to some of your points:
Yes, this tactic is called turret creep, and it is boring and unnecessary. Instead, try to get power armor, two nuclear fusion reactors, a bunch of shields and some exoskeletons. Then, use any combination of destroyer capsules (which are completely worth it! 100 destroyer capsules make short work of most enemies), poison capsules, cluster grenades and flamethrower to eliminate the base. More fire, and much more funDrakosha wrote: 4.1. I created a map 9999x9999. I was left 5,000 cells. 100+ hours of game time. I learned to fight. 2000 cells was a little interesting. Then slalom boring. I am doing one and same action. I put the drawing on the front line. The last I collect turret. I bet, pick, put, pick, put, I collect. Boring. It would be desirable to come up with something.
6.4. I do not use military robots. a lot of problems. The result is very small. I find it easier to use the laser turret.
6.6. I do not use grenades. I find it easier to use the laser turret.
You don't really need efficiency modules if you don't care about power use and pollution. However, it is quite easy now (with modules in blueprints) to add efficiency modules to mines, which is a pretty decent use case.Drakosha wrote: 5. General.
6.1. I do not use module efficiency (Pink modules).
6.3. I do not use (all) modules 2 and 3 levels. I think easier to put the second factory.
6.5. I do not use the building, which is 50% of the modules transmits factories. I think easier to put the second factory.
Producivity modules, on the other hand, are really awesome. 20-40% extra productivity doesn't seem much, until you realize that you can apply it throughout a whole stack (mining -> smelting -> copper cables -> green circuits -> red circuits -> blue circuits -> control units -> rocket part). If you fill the refinery/smelter/assembler with as many level 3 productivity modules as possible and then add beacons (the 50% building) so each building is covered by 6-8 beacons, you suddenly have a factory that produces 5 times the output in the same time and with the same amount of ore.
See e.g. this design (viewtopic.php?f=18&t=30332#p191784), with only 6 green circuit plants it produces almost 3000 circuit per minute. Without modules, this would take 20 green plants and 30 copper plants (so 4 times as many assemblers), and this design also consuming less than half the copper of a normal setup.
