Aliens are integral to the setting of my upcoming Space RPG Free Spacer. When I began to create the Free Spacer setting, I had many decisions to make about the people that would populate the Milky Way Galaxy. Would I have Aliens and, if so, what sort do I have? Here are my choices and their emergent repercussions.

Life out there…

The first and foremost question is: Do we have aliens or not? This is mainly a choice based on the possibility of life in our Galaxy. How plentiful is life and how evolved is it? Our current scientific research shows a lot of potential for basic life, even in our own solar system.  With this great potential for life, Free Spacer needs to have aliens. So what about alien people? It is conceited to believe that humans are the most evolved life form in the galaxy. So amongst the billions of different life forms in the galaxy some must be at least as evolved as humans.

What to call them?

There are three standard terms used in science and Sci-fi intelligent alien life forms, Sentience, Sapience, and Sophonts:

Sentience is a capacity to sense and/or perceive subjectively.

Sapience is often defined as wisdom, or the ability of an organism or entity to act with appropriate judgment.

Sophont: An intelligent being; a being with a base reasoning capacity roughly equivalent to or greater than that of a human being. The word does not apply to machines unless they have true artificial intelligence, rather than mere processing capacity.

So using these definitions Sentience is out, not particularly rigorous. It could as easily apply to a great ape or maybe even a cat, as they sense the outside world subjectively. This leaves Sapience and Sophont. Personally I like the word Sophont, it was coined during the golden age of Science Fiction by Poul Anderson and used by the great Spider Robinson. Sapient is a useful word as nearly everyone knows what it means. I’m going to use both with Sophont as the noun and Sapient as the adverb.

Actually Alien, but Understandable

Now that I have decided to have Aliens and what to call them, how alien do I make my Sophonts? The alieness of a Sophont can be gauged on a scale between Star Trek style wrinkled forehead humans to completely incomprehensible.

Gene Roddenberry chose to use the wrinkled forehead aliens to let his audience see the actor’s eyes. He wanted his audience to understand the aliens and identify with them. This idea is just as important in an RPG, players need to understand the Alien they are playing. Still it is unlikely that life out there will look just like humans. I want my Aliens to be much more alien than that.

One of the other pillars of design for Free Spacer is that the stories told are the Gamemasters stories. This pillar meant that I needed to have an Alien Generator to let Gamemasters easily create their own Aliens.

Having these very alien Sophonts in Free Spacer immediately ran into problems. The first issue was that highly variable Sophonts made the size of rooms and the use of devices impossible to design. So I had to create guidelines, for sapient life. These guidelines are integrated into every aspect of Free Spacer’s Milky Way. Technology, conveniences, ship design, and even social practices between societies are based on what my aliens are like.

Post-mortem

Although my aliens are not much stranger than those in Star Wars, their alieness had an interesting repercussion, explaining them. When telling players about the aliens or hiring an artist to do alien concepts, it was difficult to describe these very alien Sophonts without reverting to a silly simplification. Still now that it is done, the extra work describing these aliens seems to be working out. I have ten very different original alien species and they are looking great.
