It's harder to invent the wheel than to reinvent it.

Whenever another civ that you've met has completed a tech/civic, you get a science/culture bonus while you are researching it, and a bigger bonus if you have Diplomatic Visibility on them (e.g. spies, embassies, open borders, alliances, etc).


- The pantheon choices are all replaced with powerful geography-based beliefs with names from Greek mythology. The idea is to provide big bonuses on desolate (like deserts or tundra) or singular types of terrain (like cattle or sheep) that thus becomes your "holy ground". You also get combat bonuses on this turf, which creates a huge incentive to forcibly take over someone else's city when they aren't respecting your holy ground. Or sacred cows.

- Resources and Marshes can no longer be removed, either by a builder or by placing a district (otherwise you could just harvest away your enemy's resource type)
-- This overrides the "Districts on Resources" game option


Luxury resources provide amenities to all your cities, not just 4.


Foreign tourists provide your empire with gold per turn.


This option changes how districts provide yields. It's the people that create the yields, moreso than the buildings. A mine doesn't really benefit you unless it's being worked, so neither should districts. However, even though it now takes population to make your faith/science/culture/gold/production, you can get higher yields than before.

Details:

1) The districts themselves now include a specialist slot
2) The inherent yields from the district buildings were reduced by 1 each
3) Each building increases the yields for their specialists by 1

Consider the campus:
- Campus specialists start out making 1 Science
- For each campus building, all specialists make an additional Science, thus when you have a library and university, each specialist will make 3 Science
- The campus district itself and each building includes a specialist slot, so if you have a library and university, you can have 3 citizens working the campus tile
- Each building inherently makes one fewer Science, so now the library itself only generates 2 1 Science and the university 4 3 Science

Affected districts include:
- Campus (Seowon, Observatory)
- Commercial Hub (Suguba)
- Encampment (Ikanda)
- Harbor (Cothon, Royal Navy Dockyard)
- Holy Site (Lavra)
- Industrial Zone (Hansa, Oppidum)
- Theater Square (Acropolis)


- Water Mills add 1 food to all farms in the city (instead of the food bonus on only Rice, Wheat, and Maize)
- Water Mills no longer provide the inherent +1 food and +1 production


- Districts may be placed on Resource tiles, but placing the district (not finishing it) immediately removes the resource for no benefit
-- Note: With Olympic Pantheons, this option has no effect (Olympic Pantheons overrides the option of removing resources)


- All great merchants grant a trade route in addition to their other abilities... otherwise great merchants tend to be weak compared to the other great people. Commercial hubs and their buildings are thus more desirable.


- Lighthouses no longer provide a trade route so that they don't super-dominate markets. Commercial hubs and markets are thus more desirable.


- Never been a huge fan of the district, but especially don't like how the Grandmaster's Chapel affects the game. Faith is for making missionaries, and that's that.


- Allows you to control the amount of Science each citizen in your cities inherently generates (i.e. generated without help from districts, buildings, worked tiles, governors, policies etc.). Without this mod, it would be 0.50 (or 0.70 if playing without Rise & Fall or Gathering Storm). The default setting is 0.25 so that players have to earn science, not just automatically get it from growing cities. This also slows down tech tree progress so that you aren't developing nukes in the 1800s. A slowing effect is definitely needed when playing with the "Learn From Other Civs" option.


- Removes the tech-specific eurekas (i.e. boosts) from the game. Eurekas are now acquired only by tribal villages, spies, great people, or wonders. Slows down the rate at going through the tech tree, and your civilization doesn't have to frantically do dozens of random "side-quests" to keep up with other civs. A slowing effect is definitely needed when playing with the "Learn From Other Civs" option.


- Allows you to control the amount of Culture each citizen in your cities inherently generates (i.e. generated without help from districts, buildings, worked tiles, governors, policies, etc.). Without this mod, it would be 0.30. The default setting is 0.25.


- Removes the civic-specific inspirations (i.e. boosts) from the game. Inspirations are now acquired only by tribal villages, great people, or wonders. Slows down the rate at going through the civics tree, and your civilization doesn't have to frantically do dozens of random "side-quests" to keep up with other civs. A slowing effect is definitely needed when playing with the "Learn From Other Civs" option.


- Theater Squares get +1 culture for each adjacent district (instead of +1 culture for every two), +1 culture when placed on a tile with Charming Appeal, and +2 culture when placed on a tile with Breathtaking Appeal. They still have their adjacencies for wonders (+2), Entertainment Districts (+2), and Water Parks (+2). Makes Theater Squares more desirable.


- Monuments no longer give culture as a yield, but instead they provide the city with +2 loyalty and +100% border expansion. The Drama and Poetry civic (which unlocks Theater Squares) is moved to the Ancient Era. This makes Theater Squares more important because you can't get easy culture from your monuments.


- Builders get an extra charge when built in a city with a monument
