Biome specalists
Biomes are large geographic areas of basically the same type of terrain/vegetation like forrests or deserts or mountains. One thing that I would like to see in this game would be the ability to develop a special affinity to a certain biome. Most human culltures historically have been tied into a certain biome. Either through initial trait selection, research, or magic I would really like to see (if they want to go this route over being more of a generalist) fractions have the ability to really specialize in using and developing a certain biome.
The effect of this for the game is more differences/opions between nations. And more of the chance of growing and surviving as a weaker nation in a land of larger nations since you might have an inate advantage in your specific biome.
i think it would be great to have thoughts like this during a typical game:
"The bear-clan has reached the forrest, I won't chase them any farther since now they have the advantage"
"I will march to the gap rather than enter enter the mountains of the hill people"
What sort of biomes should have specialities? Here are some quick ideas:
Mountains, Wetlands, Forrests, Plains, Coasts, others?
Advantages: better ability to grather food in forrests. Better fight ability in your home biome. easier to build a city in this particular biome (this may allow for cities in landscapes that would otherwise be hard to support them -like fabled mountain cites or hidden wetland cities), maybe special building options?, faster movment through certain biomes, nomral monsters from these biomes might not attach people adapted from that biome "we have learned how to make peace with the mountain trolls", better defences for cities build in your favored biome, being able to see farther than normal within your favored biome (this represents better tracking ability)
What do you think?
