Throughout history trading with other nations has been beneficial in every way. For example, one of the main reasons the Europeans had a technological advancement over much of the world is due to the constant trade and intermingle between civilizations on Europe. An inversed example is the Japanese Sakoku. Japan shut down their boarders to all foreigners for 200 years. As a result they experienced no technological advancement and failed to keep up with the industrializing world. In civilization V it seems to me that trading with other civs is not as beneficial as it should be. On emperor difficulty I can easily ignore everyone and everything outside my boarders and still come out on top. Really it seems the best way to play the game is to ignore foreign politics as when I do get involved, I'm invaded and denounced. Why is it this way? I think a major problem with this is research agreements. They are too expensive and the wait is too long for them to pay off. In civ IV the instant tech trading was always essential. Those who had isolated starts or did not want to trade lagged behind. Technology is not the only problem. Resource trading could be helpful but the AI hate trading. It is nearly impossible for me to secure fair deals with them especially when all they do is declare war on me? Trading with other civs should be more important. Is this a problem with the AI's stupidity? Or does is there something else? How do you think trade can be better implemented?
