More races

[Respones]

"A baseline human, mostly unmodified by gene engineering and mostly unchanged by evolutionary pressures on non-Earth planets."
So... where the other races?
Lets make diffrent races, that have unique appearance and special trait just for that race.
For example:
- martian, with red skin, looking as Hellboy and have the trait "hard skin", that give him some armor;
- thin man, looking like thin man, with trait "thin but thick" that have less hp but have some regeneration;
and many others.

Races ARE planned, or at least outlined as existing in the Rimworld universe.

Note that the game is still in alpha stages and that work/polish is still being done on the baseline game. I probably wouldn't expect to see any significant work put into fleshing out one specific part of the game until at least beta.

Seeing as how you've used "Martians" and "Thin Men" as examples I feel like I have to point out that there are no true aliens in Rimworld.

RimWorld does not include:

    Faster than light travel.
    True aliens.

There will possible be other races of "xeno"human or ones based off of animals.

The Ordo Historia has recorded and gene-sampled thousands of differently-engineered and adapted xenohumans. Among other notable traits in this genetic library, one may find.

   

• Aquatic-adapted strains who can withstand breathing very high gas pressures and even survive days of immersion by exchanging oxygen through the skin (no true permanently-aquatic fish people have ever been confirmed).
• Soldier variants carrying any of a large number of traits that various militaries have seen fit to bestow upon their people. Typically, they have large muscles and perfect eyesight. Some have minimized metabolisms made to digest a single kind of long-lasting nutrient solution, to make army logistics easier. Their lifespans are short - usually between ten and thirty years - and they grow up very fast. But the most significant differences are psychological. Engineered grunt soldiers are obedient, sense pain only in a distant way, obsessed with learning about weapons and war, and carry a strong need to be part of something larger than themselves. They are deliberately lacking in abstract intelligence and creativity. Engineered commanders are highly analytical, fascinated with military history, utterly cold under pressure, and masters at spatial visualization.
• Radiological immunity is a very common adaptation; the Ordo estimates that most of humanity is more tolerant of radiation than our Terran progenitors.
• Some worlds engineer "perfect mates" for the rich and powerful. Such specimens are created with bodies to match the fashions of their home worlds and the tastes of their owners. They tend to be obsessively submissive and devoted, totally without jealousy or self-regard, artistically inclined and endlessly cheerful. Such traits do not last long in an unrestricted evolutionary environment because they are so easy to exploit, but engineered mates are sometimes kept in longsleep long after their creation, to be traded into a post-catastrophe market that can no longer create them. The main contact most of us will ever have with such specimens is through their descendants, who, while they have most of the traits of the original in only a very diluted form, still occasionally express Mendelian traits like impossible eye shades or streaks of multicolored hair.
• Fashion-driven genetic modifications are often applied during later life instead of prenatally, and are most often cosmetic and skin-deep. Variations in hair and skin color are common. More exotic modification add shining crests, color-changing skin and eyes, reshaped or elongated bodies, and colored nails, feathers, or fur.
• Gravity variations create new body structures. People from low-g adapted populations are lighter, taller, and weaker than those from weightier environments. The most extreme examples are the gravity dwarfs, 3-foot-tall xenohumans from worlds of over 2g of gravity. Their short and stocky shape lets them live and work in comfortably in such oppressive g-pulls. They even have a noted preference for short and underground dwellings. It's unresolved whether this preference is cultural or genetic in origin.

Such intelligence-enhanced animals are collectively classified by their degree of brain power and called by a specific prefix like so:

• Opti - Indicates enhanced but still sub-human intelligence. Optianimals can usually use tools, form long-term goals and organize into primitive social groups, but can't speak more than a few words, read, or think abstractly. Optidog, optipig, optiwhale, optimonkey.
• Trans - Indicates intelligence in the human range. Transanimals can read, use tools, form teams, hold conversations, and think about complex ideas. Transdog, transbear, transgoat, transsimian.

Bear people confirmed; get to work modders.

My God, they have Squats in Rimworld! Games Workshop has denied me them even before I was born! (looked through my dads old Rogue Trader books, they were cool. But ultimately became bug chow and retconned to hell and back.)

I need this for my ice sheet colony so I can have bears and humans in greatcoats and ushankas armed with survival rifles and alcohol addictions.

Isaac Asimov did not include aliens in his stories (I forgot the reason tho). I feel the same about RimWorld. And it wouldn't go along the Firefly vibe

My "Martians" and "Thin Men" not are true aliens. They are people modified by gene engineering or changed by evolutionary pressures on non-Earth planets
- Martians are people living long time at Mars, red planet, fighting with mechanoid,  and in time those who has more red and more hard skin will be survive. People from Mars - martians.
- Thin Men are people from Lizardy, where people are worshiping cult of Lizard, loving lizards, married at lizards, and change their own geneticist for the name of Great Lizard.
