First of all, how many races are there in the Ooniverse at this time?
There are eight types of critter.
There are nine basic categories, if you include Humans (although arguably we might just be a sub-group of "Humanoid"). In no particular order:
- Human Colonials
Of course, there's an as-yet-uncounted (as far as I know) number of species
. Me, personally, I think that the Green Horned Humanoids from Tiinlebi are a completely different species from the Blue Furry Humanoids of Edreor. It looks like only humans have extensive colonies, for some reason - although it's possible that e.g. the Green Fat Insects of Tioranin are the same species as the Green Fat Insects of Arazaes: both are Democracies, both are TL7, and the two worlds aren't even hugely far apart, both lying in the north-east quadrant of Galaxy 1. But if they are the same species, are they native to Tioranin or to Arazaes? Or from somewhere else? Humanity's homeworld isn't anywhere on the map, after all. Is there a connection to the civil war on Tioranin?
There's no right or wrong answer to any of this, of course - it's all just randomly generated. Personally, my imagined universe contains a lot of different species, each made up of many different cultures - but that's just me.
