[generic] What are you backing?

Those are species, and once the internet spots this they'll catch flak for it.
The game was in playtest for months before this public Kickstarter. So either dozens of GMs and many more Players are in on this conspiracy, or probably just the designers deliberately channeling traditional D&D classifications to attract the non-SF crowds.

The only down side to me is the chosen in-game timeline and structure focused on a limited TV series run, instead of the whole Stargate franchise. Though, maybe, that is a marketing ploy to offer more stretch goals and extra sourcebooks.
Today's post drop brings me the hardback of The Great American Witch, a Kickstarter that I backed in August, using the same system as The Great American Novel. It seems to be PbtA with an advantage/disadvantage mechanic. Looks lovely, anyway.
