I've been playing civ III for years and am mostly a solid regent player, i.e. I usually win. I've read the various strategies and guides, but I am now confronted with a situation that I don't usually find myself in. In most of my games, I set up a settler factory and expand very fast, building tons of workers to connect my cities. I usually try to get horses and iron and expand into one or two neighbors for land, so that I can spend the rest of the game focusing on culture and building. In most of my regent games, I'm done conquering people by the start of the middle ages, and by the time I'm in the industrial age I am the tech leader, the richest, most populous, and most cultured nation on the map. However, I try not build many good wonders (like great library) except maybe Smith's trading company later on. In this game, however, Many things went wrong. I am playing as the Aztecs on Kal-Els earth map, on regent, with every win condition and mass regicide. I was placed in Mexico and America was placed where it historicallys starts. We both expanded and I was able to keep up and at times out expand america, but by the time I was getting ready to attack america, I discovered I was really behind in techs (america had 8 techs that I didn't have) and they had multiple swordsmen compared to my many archers. In the first war, I was able to grab a city and get peace, and in the second war (in middle ages) I was able to grab another city in south america. after some consolidation and infrastructure building, I discovered America has twice as much land, but my empire has a higher population and I caught up in techs. But now, I'm in trouble. I never was able to get horses (america settled these areas in north america first) and has been building knights and cavalry like crazy. I've built a lot of medieval infantry and musketmen to counter him, but I can't seem to beat his armies any more. I've come to ask a few questions on how to improve my situation. I'm not used to wars in the industrial age, let alone wars where I don't have a significant tech advantage. It seems like I am going to be at war a lot of the game, so I need to know how to deal with a large military threat like this, this late in the game. My questions include: 1. What techs should i research in the industrial age if I am expecting a lot of wars and my enemy and I are one of the largest civs. 2. How do I deal with a war on a long border. My wars with america usually stretch all across the american west and southwest, and I don't have any fast units that can travel between cities quickly. 3. What governement (if I should change) should I go after? I am currently a republic with an army twice as large as I can freely support and a ridiculous amount of corruption occuring. 4. What units and how large of an army are best suited for industrial age warefare? I am in the middle of hooking up a horse to my capital in south america, so I could build cavalry soon, or should I just try and get infantry and tanks as quickly as possible? 5. Should I build a navy? America has no navy, and I have many productive coastal cities that could build a navy relatively quickly. But, I don't know how useful having a navy in this landlocked war can really be. If someone would explain how to post a saved game I'll do that. Otherwise hear are some pics.
