Ratt's Various Tweaks

Here's my first mod ever for Civ VI. Mostly a bunch of tweaks done to the game to improve a few things I felt could be done better. 1. The aim was to fix some of the more egregious balance issues in the game (like Swordsmen being able to easily beat Pikemen 1 on 1 despite having a better than 2:1 cost advantage, or Knights being better than Pikemen in every way imaginable) without changing the base game too much. 2. I also aimed to virtually eliminate all leaf techs and civics in the game, as well as to put each government tier on the same level (it still bugs me that in vanilla Theocracy and Merchant Republic unlock later than Monarchy, and on leaf civics at that). 3. That said, this mod isn't designed for optimizing playthroughs, but to streamline some bits of the game I found rough. Without further ado, here are the changes I've implemented: Unit Changes: 1. War Carts now unlock at The Wheel and replace Heavy Chariots. War Cart maintenance increased to 1. 2. Knights and Mamluks now cost 220 Production, up from 180. 3. Pikemen/AT Crew/Modern AT now cost 150/350/500 Production, down from 200/400/580. 4. Pikemen/Pike and Shot/Modern AT maintenance cost down to 2/3/6 from 3/4/8 (AT Crew remains the same) 5. AT Crew/Modern AT now have Range 1 attack, updated to 70/80 and 85/95 strength respectively. 6. Horsemen now have 32 Strength, down from 36. 7. Musketmen now require Metal Casting while Bombards now require Gunpowder (bombards came before firearms) 8. Crouching Tiger and Ma
