New game?

[Khan]

not talked about:
What map size do You want? Or You leave this to map maker, to be appropriate to number of players? Perhaps decide whether You want it cramped or have some room to peacefully expand first. And whether You want to have resource rich map? I assume You all want to ensure strategic resources reasonably close to every player.
Also, toroidal wrap has been mentioned by some.

I leave this to the judgment of others. If I were forced to choose at knife point, I would plum for room to expand and resource rich and a flat map.
