Did you ever consider removing the restriction that rails needed to be aligned to the 2x2 grid, so blueprints with rails could be moved by a single tile?

I'm not sure your logic is correct. For example, when train 2 would go to destination 2, you compute 0 crossings. However if train 1 would go to destionation 3, train 2 would have a crossing nonetheless. How I would calculate it: Suppose you have n trains and n destinations. The probability that two...

1-2-1 at the beginning, usually with single tracks for each ore patch. Later, I build a centralized station with loops, and slowly phase to 2-4 trains.

Since alien bases are already as packed as possible, but resources become better the further you go away from spawn, I would try to push as far as possible in one direction, and then scout from there.

I think landfill is grass only. Only grass has a tile transition to water, see https://www.factorio.com/blog/post/fff-199.

You can blueprint landfill? It used to be possible to do that, but the devs changed it because they don't want you to abuse landfills or something like that. The reason they disabled it is because it was bugged. The bots left holes and landfill blueprints remained on land. They said maybe in the fu...

It changes to stable when the devs are happy to call it stable (i.e. most bugs fixed, no pending issues). I'd except a stable version a few weeks from now on.

Before, there was an output slot always visible. However people put satellites in there (instead of the satellite slot, which was already only visible once the rocket is ready), thus blocking the output slot. So to prevent this, the output slot is only visible if there is actually some output.

Around 2-3 hours, normally. But sometimes the flow gets me, and I'll play Factorio all day. After a patch, I'll think of Factorio a lot for 2-3 weeks, but then other things take over

The rocket actually is the superstrucutre. But something a few magnitudes more expensive and bigger would be nice; the infinite research is nice, but a bit lackluster at moment.

As a long term player, I fully agree with the suggestions, and I'd like to have the new GUI rather now than later :) The suggestions make an already very polished GUI even better. The only really quirky thing at the moments are blueprints. Among other things it's not possible to show the inventory a...

You can remove the restriction for concrete placement in the lua files (I did it once, but I forget where exactly, I can search for it if you want); I don't know if there is a mod that does that. However placing concrete next to water sometimes bugs the water edge; the problem is that Factorio handl...

I don't think that chaining pumps makes any sense. If you don't do that, the unloading is more more slower. Actually, if I understand Factorio liquid physics correctly, inserting a single pipe segment between two pumps should not affect pumping speed. Pump moves 200 liquid per tick, which is exactl...

Suppose you have a missile with an explosion radius (35) greater than your shooting range (25), and it kills everything inside that radius, so you actually have to run away hard after shooting it. And supppose you have 200 (or as much as you like, really) combat robots that do twice as much damage a...

To make the transfer very fast, connect each segment of the liquid wagon to it's own storage tank via a pump. You can also chain pumps (but don't use pipes in between). It should only take a 2-3 seconds to drain/fill the wagon that way.

Edit: Added screenshots

The factorio character is obviously immune to radiation, as he can carry around nuclear waste without problems. Aliens are probably immune too, so they don't care about atomic bombs as much as for example about flame throwers burning their precious forests.

The whole blueprint system is clunky and not very intuitive anyway now, as it's a mix between the old item-based system, and the new library system (and there are two library pages with slightly different aspects). But still, it's an improvement :) I hope the devs will improve things at some point, ...

And you could use heater-tank-engine as an accumulator replacement, so it has other uses

I agree, iron sticks don't really have a purpose in the game, except at being annoying. Some people like tons of intermediate products, but some mods scratch that itch much more than vanilla.

But maybe I'm biased in that I don't really like intermediate products with only few uses

To begin I use double headed trains with 2 wagons (1-2-1). They are easy to set up and have enough capacity for short routes, and it's easy to run different trains for iron/copper/oil. Once I get outposts farther away and a higher resource demand (say >5k iron/minute) and robots sort the ores, I wil...
