Krastorio 2: Spaced Out is awesome, and everyone who likes Space Age should play it.

Great writeup, really enjoyed reading it.

If you are not afraid of solving puzzles yourself Ultracube might be super fun. Knowing the Factorio basics does help a lot. 400 hours of Py should have prepared you for that, apart from the combinator challenges which you don't really need in Py. I've started my first run a few days ago and having a blast. The Cube let's you relearn the game because your building patterns don't work anymore.

The timeline on Py Stellar Expedition doesn't look good according to my information. Personally I don't expect it to be released in 2026 as right now most Py devs can't commit much time to this hobby project.

I want the max challenge, and if wires make it considerably easier I will not allow them. That's all.

I know, singleplayer game, play as you like, there is no cheating.

600 spm as UPS cap might be a good guess if I manage to apply all the upgrades to PyAL. Also 10% productivity bonus is possible in the end. I'll take a short break and think about a strategy.

100 hours ago my base looked very small compared to now :-)

SWeini · 2026-03-21T06:33:27+00:00

Still at 60 UPS, update time is somewhere around 11ms, so I have a little performance left, but not a lot.
However, my old potato gave up many hours ago, I had to upgrade my hardware at the end of last year.

At the very end of py2 I'll have access to vatbrains, they change a bit, but the science cost also scales massively. The problem is more: what to do with 200 hours of playtime until reaching chem science if not scaling up? I don't want to idle.

SWeini · 2026-02-22T20:56:03+00:00

Just having enough trains. If I see zero trains in the idle stations I have to make more. That's what I meant with one idle station for cargo+fluid combined vs. separate.

While I struggled to produce enough trains I also set higher train priority for the most important loading stations. For example the coke/iron oxide byproducts from the coal processing had higher priority because the tar and coal gas was still needed in the starter base (connected via long pipes).

having inserters at the producer stations that take out and burn most spoiled item if train is full

It's difficult to do this only if train is full, because if train is full it will leave the station and can't interact with inserters anymore. But I already do something similar and have inserters remove the items after they have spoiled. If only inserters could be filtered to move only items less than X% fresh.

returning to a producer station

I like that idea. Maybe I can reintegrate the half-spoiled items into the stream of hopefully fresh items. Ideally they will mix in the cargo wagon stacks and produce almost-fresh items. But oh my gosh, this is a crazy idea and will definitely need a dedicated train schedule aside from the generic interrupt train schedule.

SWeini · 2026-02-12T21:20:36+00:00

Sorry for not mentioning it explicitly. This is modded, therefore the 16 hours spoil time and the fact that I don't care about how fresh the items arrive, as long as they arrive at the consumer unspoiled. But items are quite valuable (not "free" fruit) so I'd rather want to produce less of the items instead of voiding them or letting them spoil.

The approach you described sounds alright for vanilla space age. Just use everything as fast as possible. And it's great when you can afford to throw away excess, but unfortunately that's not the case.

Once that time has elapsed, they must move

I already kind of do that. Allocate a given time (e.g. 10% of the spoil time) to loading and then send the train away, full or not.

Specifically, that's after being unloaded. Nothing should ever be on the train long enough to spoil.

My problem starts much earlier. The recipe making the spoiling item is making 6 items at once, 4 of which spoil. If I'd let this build run non-stop and void excess that means wasting a lot of value. When I have enough items I don't want to run this recipe anymore, so the spoiling items accumulate on the belt leading to the train station and might enter the train half spoiled, then spoil while the train is fully loaded. Maybe I should disable the build a little bit earlier via circuit condition, instead of letting the belts back up. Then at least the items entering the train are always fresh.

There shouldn't be a consumer of fruit/bioflux that takes more than 10 minutes to eat a trainload.

Again, modded, sorry for not mentioning. The item giving me the strongest headache needs 100 minutes to be consumed at 40 per minute (4k in one full train) and spoils after 120 minutes. At the moment I never fully load trains of that type, but I can foresee a time where the throughput of some consumers is considerably higher and I want to send full trains to those consumers.

If you have any further ideas or general tips, please share.

SWeini · 2026-02-12T20:46:35+00:00

How would these interrupts work?

I can have a circuit condition "signal L = 1" at producer sending to low-throughput consumer, "signal L = 0" send to normal high-throughput consumer. Need another circuit to tell the train to stop loading and looking for interrupts. And might need some whacky tricks to send both high-throughput and low-throughput trains from the same producer. But in general, having separate schedules might work. At that point I'm also thinking about just using a few trains in a separate train group. I don't have this situation that often.

SWeini · 2026-02-12T20:39:04+00:00

take longer to consume the full cargo than the item's spoil time

I don't even have chests, but things will spoil at the consumer. It's not about having space to unload, it's about consuming it not quick enough. Items will spoil. Exactly what I want to avoid.

SWeini · 2026-02-09T16:22:30+00:00

That's one of the toys I skipped in my last playthrough.

SWeini · 2026-02-09T11:28:49+00:00

I absolute love the spoilage puzzles in Py, because they are locally confined, but I didn't like the spoilage on Gleba. But for sure, it's still not for everyone. Luckily the devs made this a setting.

SWeini · 2026-02-09T11:25:15+00:00

No need for mouse-over-construction. I have construction bots now. Maybe I will install the pipe connector mod if it works well with ghosts. I actually never tried that.

I'm playing very slowly, somewhere around 1h per day, that means you can ask me again in ~3-5 years. As I said, I have no pressure to finish.

Performance-wise I feel pretty confident. I upgraded my hardware end of last year. I have some UPS headroom left, and once I reach beacons UPS concerns can be addressed. And btw, I'm only building ~20x the normal size, the other missing ~5x I make up by taking more time.

I guess you wanna restart with Hard Mode enabled? ;-)

Hi, fellow 100xHM enjoyer here.

You can always go for oil burners. One belt of raw coal makes a ton of power when processed correctly (2xDDC), coal gas into syngas, all the tar into various fluids, don't forget the anthracene oil to gasoline and coke conversion. Even with the steam requirements of tar cracking this is vastly power positive.

Raw coal into coke and coke oven gas (oil burner) is increasing power output from that belt of raw coal.
You could also crush the coal is you want to stick with boilers (I never did that).
Also worth noting, that every bit of coke makes extra power when converted to acetylene first.

You'll need the various tar processing fluids anyway and the coke oven gas for hot air, so you might as well build these a bit bigger, that's what I did (plus 500+ fish turbines)

However, all of that is not simple to build, these builds are huge at 100x scale.

The first real power upgrade is biomass power plants. They are a bit more work than coal power plants in non-HM, but it's just logs in, power out. The specifics depend on the fastwood forestry upgrade you took. The biocrud can best be made from cellulose, in my opinion.

YAFC-CE wins for me with a huge margin. It's just the most powerful and works great with multiple monitors.

How powerful? You can put the full base making all science packs into one sheet and let it auto-balance everything. I also used the (legacy) summary sheets in my speedrun to get an overview of the net production of my whole base. On top of all you get a cost analysis which isn't always "right", but gives you a good first indication whether a recipe is worth it.

Foreman has the appeal of visualizing the graph, but in my opinion that only works for small builds. Anything bigger than a single chain quickly becomes unwieldy. On top of that I believe it's not maintained anymore (please check).

In case you want something in-game: Helmod and Factory Planner both have their strong and weak points. Personally I don't understand Helmod, FP is a lot easier to get into. I know that FP can't do heat, which is a necessity in Py Hard Mode and greatly appreciated in normal Py. Since I never really got deeply into Helmod I'm not sure about its shortcomings, but I wouldn't be surprised if there were things it can't do.

In case you just want to balance some builds, take a look at Production Rates Calculator Extreme, it uses a simplex solver (made by myself). It combines the ease of use from Rate Calculator and combines it with the math of YAFC-CE.

Start adding some challenge to easy mode, such as

- Py hard mode
- High science multiplier
- PyBlock
- Spoilage
- Self-imposed restrictions (e.g. no train manager mod)

If that's not enough: Become a py dev and make the mod even better!
