Thank you for doing this poll. If I remember correctly, then the average time for solo play during our external playtesting was a wee bit below an hour.
My average solo game is about 50 min.
Whenever I play, I figure out my turn, and then rapid-fire play the Automa, so it is always "my turn" (if I get distracted and leave the table, no confusion about the Automa having done its thing already).
Rarely, if I paint myself into a corner (with some of the odder board/faction combos) 60m.
