I really enjoyed this game, but somthing is missing and that is resulting the world in we are playing feels dead. It is not enough that an story event comes up and says me its raining I want to see myself how it is raining. The only thing we are getting advantiges of the world are the resources, where we are settling and building districts. Here are some ideas to make the world in Humankind more lifelike, enjoyable and maybe frustrating.

Day night cycle

• At night the eye sight of units, citys, districts, outpost are lower and is used for ambushes and stealth for non stealth units.

• New technologys like "night guards" for uncovering intruders and "city lighting" for increasing the eye sight, but not fully.

• Another thing that is importent is that an turn ends it is not suddenly night or day, it should be a slow and constant change from day to night. For example a day last for five turns, one turn its sunrise, sunset, the sun is on the top and inbetween (some small detail while one site of the world its night on the other half its day, the sun rises from east and sets in the west).

• Night and with it stars can be used for navigation on the sea, i dont now how to implement it in the game its just an idea that should be said.

• Solar eclipse, blood moon, aurora, meteor showers, are nice to have and can be used for faith and dont give us strategic advantiges and disadvantiges.

Weather

• Rain should give us an food buff and to much rain results in floods that can damage or even destroys our citys and districts (at rainy nights city lighting is not functioning and MG units of the early modern are useless).

• Thunderstorms the same as rain, but with tunders what can cause forest fire and damage units.

• Fog is decreasing eye sight and can be used for ambushes and stealth for non stealth units like at night.

• Sandstorm and snowstorm pretty the same decrease of eye sight, movement points, combat strength and maybe are damaging units.

• cloudy, haze and blowing snow i couldnt think of strategic uses so just nice to have.

• In the early game weather should be unpredictable and in the late game with a new technology "predict weather" we will knowing how long where and at what time a weather change is taking place.

Seasons

• The southern hemisphere should have the opposite season of the norhern hemisphere and on both sides of the earth equator are only rain and dry seasons.

• Winter especially in cold regions should harshly decreasing FISM, movement points, combat strenght of units and can freeze lakes.

• Summer is the opposite of winter.

• Rain seasons is a longer lasting rain that can cause a huge increase of food, can create new rivers, rising sea level of lakes and can cause very damaging floods.

• Dry seasons are causing a huge decrease of food, rivers and lakes can dry out.

Natural catastrophies

• Volcanoes should be added to the game and volcano erruption causes massive destruction in its surrondings, but the benefit after an erruption are new resources are appearing like volcano ashes that gives an food bonus, basalt that gives an industry bonus and salpeter. In the late game volcanoes can be used for power plants.
• Earthquakes are different strong, some causing minor damge others destroying whole citys and are able to terraform the landscape. Earthquakes are used for science, because they are telling us about the earth interior.
• Tornados are only causing destruction.
• Tsunamis are occuring from volcano erruption, earthquakes and meteors. They are only causing destruction.
• Meteors are landing on our planet causing damage depending on their size and leaving behind craters and maybe iron, they can be used for increasing science when a scince dicsrict is build next to it.

Please consider that the ideas arent thought well and can be improved by you. I hope i was able to give the devs an direction where the game can go.

I wish you a nice day
