The Nomads were artificially created. The Dom Kavash are the only true alien race we know of, and life in the universe would be few and far between.
If you are RPing Dom Kavash, you are basically roleplaying something that could destroy a whole House in a heartbeat. It would be like trying to roleplay the Star Child from 2001: A Space Oddysey or Q from Star Trek.
yeh... well.
I'll change my position to:
as long as it remains only a rp stuff. Meaning: no alien faction being created. Maybe, just maybe npc if its really worth it. But no player.
And no need to say it'd need one heck of a large rp to be acceptable...
I'm referring to the probable rarity of alien life. Francis Drake, a fairly optimistic scientist in said field, estimated that only 10 intelligent species would exist at one time in the whole Milky Way Galaxy. Sirius is just a tiny sector in the Milky Way, which is made up of hundreds of millions of stars, as opposed to maybe at most 150 in Sirius.
no, it's mainly because I have a feeling players are too spread among factions here, since you can join many faction at a same time. that would make less people for human played factions - which are, admit it, the main race of freelancer.
I'm not saying players cant roleplay as those aliens you suggest. Just not pilot as these aliens.
Or restrict these players at the extreme by requesting from them very good rp skill, whatever.
