Time for the monthly shot in the dark.
I think it will be a standard map # of land tiles, but maybe on a physically larger map with more water distance. I'd expect a modified continents layout, with more islands than a normally generated continents map has. Cold and wet, maybe with a somewhat artificial land mass which is mostly tundra, hills, and mountains with a grassland border, to represent Greenland. A much smaller island which is all grass and hills except for some mountains and volcanos, to represent Iceland. Expect hills/mountains with the new resources from the goats family, and coastal rocks.
For opponents, Celts, England, Germany, France, Russia, Greece, and America are musts. Given the past couple of months, it is reasonable to expect one or more civs to be boosted or ******** in some way.
It would be interesting if the Tournament (medal play) objective was conquest. That would fit in with the ancient Viking image of looting and pillaging. There should also be workers available to enslave, maybe a repeat of the workers hidden in mountains thing, or the barb camps with workers. Speaking of barbs, probably restless if not raging.
Game level may be regent if the land is really bad, or maybe another Monarch but with different Conquest bonuses and Predator handicaps.
It will be interesting to see what percentage of players choose the designated victory condition for the medal play series. This time around it might be something hard to achieve from this start. Or something ironic, like culture as a counterpoint to the Vikings' militaristic tendencies.
