It'll be interesting to see how terrain and environmental interaction affect siege dynamics. For example a siege of a swamp city could see the defenders loading up on electric skills and zapping the water attackers have to stand in. Fire skills are weaker in cold climates so building with flammable materials might not be a bad idea (assuming different building materials have weaknesses). Having a frost mage sneak an army over water for a surprise night time assault might be a thing we see.
Trade-wise, I think frost spells will be end up being a requirement for traders because it will allow them to bypass bridges in dangerous areas, and generally allow them to take unpredictable routes over water.
@therippyone said in Biomes, Terrain & Climate:
Or, maybe there are "basic" roads, and people can improve them so they allow faster motion, or something.
According to the latest Q&A, that's exactly the case. There are already paths between city zones that can be paved into roads, and these roads decay and have to be maintained.
