Being a witch in space was a lot more interesting than I expected! I tend to stay away from science fiction (especially hard scifi) but Familiar Unfamiliar wedded witchcraft to generational spaceships seamlessly, and for once I felt very natural playing in a scifi space.
I used the Way of (Tarot) Cards but at some point I want to play again with the throwing stones version instead, though using the Way of Cards can let you draw more from your own familiarity with the cards if you want.
I found the mechanism of 25 casts/cards divided any way you see fit among the 7 parts of the game freeing after I got used to it. Some folks may get hung up on a specific cast result, but it's much easier to think of each phase as a different freeform tarot-style reading rather than indicating specific questions or elements in the game text.
