Hey all,
I've been lurking for a while and this is my first post, and if I'm repeating something previously said, please forgive me. But I was thinking about the trade dynamics between cities and between kingdoms and something that I think would be interesting that would help differentiate Elemental from games like Civilization is if trade routes between cities developed organically. Instead of sending a worker or an engineer or something out, if you built another city or developed a trade agreement with another player, you could see a trade route or road develop over time between the cities and you could tell the value of that route by the level of road development or the number of caravans you could see on it.
Aside from the cool visual effect (at least, in my opinion), I think this could also present a lot of strategic opportunities too. For instance, if multiple trade routes intersected at a point and you put a city on that intersection, that city would get a big trade bonus and perhaps a tech bonus too. Also, if you were in enemy territory and you saw a trade route, you could raid it for money and hurt the trade of your enemy. The concept I'm drawing from is bascially the various Italian city-states of the 17th and 18th century that were major trade, technology, and culture hubs between Europe, the Middle East, and Asia.
So, hello to everyone here and let me know what you think.
