Judging by where Unturned is seemingly headed in terms of its art style: the answer for build details is definitely somewhere in between but closer to “more like the farming mod”.
Presuming the question requested a scalar analysis.
(Obligatory introduction)
Chairs & Tables
Ever try crafting something standing up?
No. Everybody here is too lazy to even attempt that!
Well, I did. It wasn’t very easy, you only had your two hands, and maybe the ground if you don’t have a table/machine/utility near you to assist your construction.
But the distance between your arms, and your construction material when constructing while sitting can be a nuisance to work with.
Which is why a table is useful, it also allows you to get a better look at your work but that’s not particularly important.
But why are chairs useful?
So that you aren’t uncomfortable on the ground for one, and you yet again, get more space to work with depending on the table’s height.
Chairs aren’t particularly useful in this sense, now that I think about it.
Why am I sitting?
Storage
Ok, I finally mustered up some ideas!
Reason for smaller storage I could see is the potential that it could probably be moved with ease with the items inside of it.
Maybe stored in vehicles it could be useful to quickly unload many supplies as opposed to having the small inventory of your person deliver the loads separately inside?
Larger containers have the benefit of being heavy and harder to move, and of course being bigger.
They would also be heavier depending on the weight.
Of course, you could also bolt larger containers down.
There could be different variety of large containers, from armoured to unarmoured, for the sake of weight
Carpets/radiators/fireplaces
Let me start by saying that it is a stupid idea to put a campfire or torch inside your base, not without adequate ventilation, which is why fireplaces exist.
So that you don’t die from asphyxiation.
Carpets are pretty self-explanatory, they provide warmth for the person who steps on them if they don’t have footwear (in which case they provide less) or are in a cold environment.
Good for spawn rooms in colder environments; the entire base if you don’t have the means to produce electricity.
If you’re really desperate, you could probably lay down on a carpet to get that extra warmth.
Depending on where the carpet is placed, it could degrade over time thanks to bugs eating it.
Radiators too, they use steam running through the radiator to disperse heat around the room.
You could always just be in the presence of a hot pipe, too.
Piping
This is most troublesome.
It could probably work if floors/walls were given a grid to snap pipes onto or simply allowing them to be connected through walls & floors/roofs, likely the latter though. The former would be a pain in the ass.
But anyways, as if it hasn’t been emphasized in the other sections (which you presumably read): the pipes give off an amount of heat or cooling dependent on the status of their contents, which thin themselves out & reduce their affect dependent on how much space your pipe gave them to use and how much of the contents are in the pipe.
Then there’s electrical pipes, which should be self-explanatory.
Renewable Energy
You know, the kind which isn’t used as commonly. Hydroelectric, solar, probably geothermal, and wind power.
These all have their benefits, scaling accordingly to their regions, however they may not be as efficient as non-renewable, such as coal, oil, & gasoline.
Luckily, there’s no environmentalists to spit in your face this time, if you do consider the latter! Or are there?
But anyways: places with lots of sunlight & panels which rotate according to the position of the sun produce more energy for the solar panels (although it must be said they aren’t very efficient irl).
Windy places like the highest points on maps or fields would be good for wind power.
Rivers would be good for hydroelectric.
Non-renewable Energy
The bad part about non-renewable is that you actually have to scavenge for it, hnnng.
Although it’s much better than renewable energy in its energy output.
And with enough output you’re probably going to be signalling everybody nearby that your base does in fact exist and it is stuffed with resources.
And then of course: there’s the fact you need to set the damn thing up, it’s not as easy as the renewable resources to set up, too (excluding geothermal).
Although on the topic of ‘unclean energy’, Nelson could probably do what Factorio does when you have too much non-renewable running, but that’s implying that your group can collect enough of it to actually warrant zombie interference, but why consider adding this? Because this: https://trello.com/c/yQ1d5wmc/9-turned.
The Goddamned sinks/water pumps
Really simply: it’s just a pipe outlet which allows you to pour nitric acid on your skin
if you want.
If you didn’t get the idea from that sentence: you can wash your hands and get a lesser chance of getting sick by touching food which you would put in your mouth with them, assuming Nelson would add cleanliness/dirtiness to Unturned.
Other than that: it’s just a way to collect water using the pipes, the sink being the same except it can be used for storage, too.
I want to power a torture device with a static bicycle.
Is it wrong that I find this funny?
Where's my fucking fortnite dance?
I’ll get more soon enough (in the course of a few days?), that’s all (for now).
