The data presented here was pulled from the game files, and I've done my best to translate it into something readable.
There are probably going to be errors, I've noticed a few while translating the data, which are bugs, some could be me mucking up the translation process.
This is also presented with data from the 0.12.1.10 patch and could change drastically in later ones.

I'm not listing any solid numbers here unless I know 100% what the effect of it is.
I can tell if it's a positive or negative effect and have listed them as such, sometimes with a quantifier of slightly, which means it's modifier was roughly 1/4 that of the usual one.
The reason for this is that some of the modifiers were listed as 0.2, but is that processed additive or multiplicative to the stat in question, if the initial stat is 1 then there's no difference, but if it's 10 then that could be 10.2/9.8 or 12/8.

There are many stats to track with your character, the sim is complex and the devs are trying to make it as realistic as possible, to a point.

The best way I can figure to describe how they work is that our stats accumulate points and once we pass a certain threshold, the stats state changes in severity.
These severity changes are what we see when we get tired or hungry and determine if we have any buffs/debuffs assigned to us because of that.

A lot of the traits are supposed to adjust these thresholds, allowing us to accumulate more or less of a particular stat before it changes state.
They also affect how we interact with Npcs and which options we have to do so.

Skills do the same with an even more narrow a focus, and not even half of them are implemented or available to us. They usually provide a bonus to one or two activities, or are supposed to unlock certain actions or socials.

Conditional states are use by the game to both show a rough estimate of a stat, and to decide whether that statistic has changed enough to affect others.

Are you Hungry? Thirsty? How much can you ignore and when will it impact your performance?

I'll expand on this more later.

The 10 Mental/Personality stats are:
Achievement, Altruism, Autonomy, Contact, Esteem
Family, Intimacy, Meaning, Privacy, Security, Self Respect.

These represent your current needs to ensure you are a sane and well adjusted individual, not that disregarding theme will do much for the moment, but that could change in future updates.

There is also a hidden Weird stat that measures/governs roughly how Sane you are.
The more you get exposed to disturbing stuff the worse it gets, we can't see it except in the message log where we start becoming superstitious, paranoid and then broken from reality.

Currently letting them fall into the red does nothing unless you smoke, in which it will increase the craving for a cigarette, it may also cause you to crave a cigarette if you don't smoke.

Where as 5 of them are supposed to give you a mood bonus should you max them out: Autonomy, Esteem, Family, Meaning and Security.

Over time and when not interacting with anyone, Autonomy, Privacy and Security should naturally restore themselves, the others slowly worsen.

In case anyone has issues seeing the G/R spectrum the game uses to denote good/bad, I've listed out the states here from Best to Worst.

There are a tonne of physical stats that can impact your character, ranging from obvious like tracking how much food you've eaten to slightly more obscure like how much blood you're likely to regenerate over night or how much radiation you've been exposed to.


I'll be explaining some of the ones the starting traits affect below, but I'm planning on returning to dig into the rest at a later date:

There is a stat to track how Threatening we are to others, which should make it easier to get them to surrender in combat, but I haven't found the interaction yet.

There's a stat that tracks how comfortable you are when you try to sleep, which is supposed to determines whether we get a buff from a refreshing night sleep.

The game actually splits our hunger into three parts, one that tracks how hungry we are, one that track how full we feel and one that set how much food we burn every x amount of time.
I mention this as there are traits that adjust fullness and the rate food is used, but not Hunger.
The Hunger/Fullness stats are linked, two parts on the same axis, we can't increase one if the other exists, so when eat and zero out Hunger, it starts adding to the Fullness track.
Too far into Hunger and we start starving, too far into Fullness and we puke from over eating.

Our stamina is also gauged with 3 stats, but they aren't aligned.
One to track how much we have, one to track how fast we recover it, and one to track how much extra we use when we do something.
Stamina and recovery is understandable, the last one is a bit different, the usage one modifies the stamina cost of actions and makes them cost more/less depending on it's modifier.
The biggest one here is usually from wearing EVA/Pressure suits.
Pressure suits add a 25% increase to stamina used and EVAs a 50% increase to stamina used.

From what I can tell Wounds are dealt with similarly to everything else we've talked about so far.

We get damage inflicted on a body part, and it tracks how much we get, then it passes the threshold and shows us a wounded condition, we suffer enough blood loss and it'll show us a different one, etc.

These wound conditions would then accumulate penalties on our other stats until we pass out or die.

There's ones that track infections, blood amount/loss, body temperature, blunt/cut damage we have taken and how much pain we feel.

Old wounds will also occasionally flare up and cause us to suffer pain and other side effects for a while.

Too much Pain can impact how fast we move or work, how well we fight and eventually knock us out when we go into Shock. And the other things penalties pain applies along the way might very well kill us.

I'll cover these in more detail, probably in another guide.
But long and short of it is that the traits you pick up during character creation affect more than just yourself.
They affect how you interact with others, there are a lot of social options that require you to have X, but are forbidden if you have Y.

There are even traits that, for the moment, do nothing but affect your interactions with others, they are:

Charismatic/Repulsive
Genius/Obtuse
Forgiving/Vengeful
Beautiful/Ugly

For better or worse, I will note that Apathetic and Shy seems to impact about 4x the average number of actions that traits usually affect, Gregarious and Oblivious affect 3x.



There are also Skills coded which should do the same as the Traits:
Languages : Mandarin/English
Etiquette : Folk/Military/Oligarch/Spacefarer/Street

The skills don't seem to be coded to interact with anything yet, but they might be in a section I haven't figured out yet.

These are just how these Traits impact you, I'll be doing a different guide for the social aspects.
I've paired them up with their opposites, the ones that they lock us from taking when we get them.
Not all traits are made equal, and I haven't listed the impact these have on social actions, as I haven't tabulated that data yet.
When something has an increased need, that means the Threshold for the stat is lowered, this means we'll need to interact with others more often to top up our social needs.
Good for a ship with crew, less so for a solo player.

These trait primarily affect your physical body and health.
Note: there are two Stat Thresholds important to surviving accidents and Combat.
These are Pain, as you pass out if you feel too much pain, and Damage/Wounds, which sets how much you have to get hurt before you start accumulating the wounded states on you body.
In most cases this changes by only a couple of points, but that change could mean you tank a hit and don't get hurt this time, or you're now cut and bleeding.

It takes 2 years switching this from Fragile to Tough, but if the math is correct, you can take 50% more damage before being wounded, it's worth is up to you.
