This is the classic map, using the same map as the Civilizations map.
A dense tropical rainforest. You can only farm on the floodplains and during the dry season. Wildlife is deadly here! Stay away from panthers, mosquitoes (as they carry malaria) and ants (will eat your food). Crossing rivers without a bridge is considered unsafe - piranhas are abundant.
Jungle biome on West side, Desert biome on East side, separated by mineable mountains and a small patch of clear land filled with alligators.
Snow plains with frozen rivers and lakes. Rock is more abundant than wood. You may encounter wolves, deer, bears, penguins, goats, mammoths, and dogs. Summer lasts only 1/4 of the year, the rest is winter.
A combined map with no oceans dividing the biomes, excluding mountain ranges.
The biomes are, from North to South:
Tundra, Taiga, Temperate, Semi-Arid, Desert, Savannah, and Jungle
