courtships are done after all the other hunts have been resolved
This is not so. Hunt order is:
1) Uncontested courtships and uncontested non-predator biomes in any order.
2) Contested courtships and contested non-predator biomes in an order decided by the first player. Players on contested cards roll in least hunter order.
3) Predator biomes in an order decided by the first player.
However am I also right in thinking, I can court a foreign daughter and if successful, I return the courting hunter to my unassigned hunters and place one of my hunters from the deadpool as a new mature husband?
I posted a solo variant a couple weeks ago that allows promiscuous species to attempt courtship with their own wanderlust hunters in another species's tableau. It seems to work pretty well to add some more decision points to the solo game.
