Released! I'd like to show off a mod I've been working on for about a month now called Agricultural Revolution. It's a semi-total conversion mod in that it changes how you play the game quite a bit. Agricultural Revolution reduces the food yield of all terrain tiles by 1, slowing early game growth and changing the focus of early gameplay to farming. There are a number of additional changes to eurekas and inspirations, as well as tech-requirements to be more historically accurate. Requires R&F, Nubia, Vikings, Indonesia DLCs I'll try to create an exhaustive list of changes.

Each civ can launch up to 5 communication satellites. You must have launched the earth satellite to start this project. Each one grants a +10% boost to global tourism. UPDATE (As of Feb 7, 2019): -Keshig now also requires horses to be built -Units should be able to embark upon researching Celestial Navigation or Shipbuilding. With shipbuilding requiring Construction, it became much harder to deal with small-island starts, so this allows you to get off your little island faster. -All civs and city states should spawn on rivers more frequently now -Civs with unique units that require resources are more likely to spawn near those resources. -Civs which previously had river spawn biases are more likely to spawn on rivers than civs which didn't previously have river spawn biases. UPDATE (As of Feb 18, 2019): -Updated to Gathering Storm -Canada gets +1 culture to Breathtaking tiles -Many military units have had their resources rebalanced. Most require Iron. Gunpowder units require niter per turn, not up front. Mounted units require horses per turn. -Horses and Iron have a base yield of +3 per turn -Feudalism gives an additional +2 horses per turn per tile (total +5 per tile) -Industrialization gives an additional +6 Iron per turn per tile (total +9 per tile) -Industrial and later era naval units require very high quantities of iron (190 for carriers, for example) -Eiffel Tower requires 55 iron to be built -Golden Gate bridge requires 250 iron to be built. -Planes require aluminum up front and oil per turn -Some re-balancing to the yields of some buildings. -Broadcaster Center has no culture yield when unpowered -Encampment buildings increase stockpile size by +15, +25, and +35 instead of all by +10. -Shipyard increases stockpile size by +15 -New building in the Industrial Zone called Warehouse. Increases stockpile by +25. Unlocked with Mass production. -Buttress no longer requires mathematics and shipbuilding, and isn't required for Cartography. Buttress requires Castles. -Cartography requires Shipbuilding, Education, and Military Tactics. Updated March 3, 2019 Overview of changes: slightly decreased horse and iron generation, increased iron consumption in the late game. minor fixes and tweaks to units and techs. -Warehouse provides +1 production in addition to increasing storage capacity -Reduced science yields from Research Lab and Hospital -Factories now consume 1 iron per turn while operational. This is to imply that your factories need raw materials like steel/iron in order to produce goods or tools for your people. -The base yield of iron is now 2 per tile instead of 3. Industrialization still increases iron yield by +6, giving a final value of 8 per tile instead of 9. -The base yield of horses is now 2 per tile instead of 3. Feudalism still increases horse yield by +2 per tile, giving a final value of 4 per tile. -The coal power plant was moved out of Industrialization and into Electricty. It made no sense that you were generating Electricity from coal before the invention of either Steam Power or Electricity. -The Oil Power Plant has been moved to Combustion. -The Castles tech now correctly requires Engineering, not just Construction -Military Engineering requires Engineering -Combined Arms requires Flight -Niter's base yield is +3 per tile, and this increases by an additional +2 with industrialization. I forgot to mention this upon the previous release -The boost for irrigation can be done with Terrace Farms or regular farms instead of only regular farms. The Feudalism boost still only works for regular farms. -Many late game buildings and wonders have resource requirements now, usually iron. They are as follows: -Factory requires 15 iron (consumes 1 iron per turn, as previously mentioned) -Stock Exchange requires 6 iron -Broadcast Center requires 15 iron -Seaport requires 7 iron -Film Studio requires 9 iron -Research Lab requires 10 iron -Hospital requires 10 iron -Hydroelectric Dam requires 30 iron -Stadium requires 30 iron -Coal Power Plant requires 15 iron (10 to convert from a different power plant) -Oil Power Plant requires 20 iron (15 to convert from a different power plant) -Nuclear Power Plant requires 30 iron (20 to convert from a different power plant) -Airport requires 20 iron -Workshop requires 4 iron -Big Ben requires 30 iron -Broadway requires 20 iron -Ruhr Valley requires 40 iron -Sydney Opera House requires 30 iron -Amundsen Scott Research Station requires 35 iron Updated units which previously did not have resource requirements, such as support units and some late game units. Side note: previously, infantry consumed oil per turn. I think Firaxis did this to imply that in the modern era, military units move around in cars rather than on foot. The movement speed of Infantry is still only 2 tiles though, which is the same for all units walking on foot from previous eras. In line with how I've changed military units, Infantry now consume niter per turn, not oil. The Supply Convoy however DOES consume oil per turn. Since it increases the movement speed of adjacent friendly units, you can think of this as the new way to get your infantry on four wheels, by pairing them with supply convoys.
