Didn't realize a new thread had been started.
For nation, I'm good with MA as that is what I have been practicing but I'll list my full picks here.
EA: Lanka
MA: Mictlan
LA: Man
As far as map goes, I'm good keeping it as Biddyn. The map has 81 land provinces, which with 5 players gives us all 16 provinces each (not counting water), and includes additional cave provinces for Solops/Agartha. I'm also down to play another map, but I've had terrible luck finding midsize maps on llamaserver as for us to use them they have to be both uploaded there and have a download link for us.
As far as thrones, I think the 6 thrones, 5 points to win with 4 level 1 thrones and 2 level 2 thrones has worked well; but I wasn't part of last game's throne rush so I don't know how well it worked out for those participating in it!
