For example, settling a coastal city sparks a Eureka Moment for Sailing. Most technologies and civics have a goal related to their subject that will spark a Eureka Moment when met and substantially reduce the research required. The Eureka Moment mechanic accelerates research time for the Technology and Civics trees.Progress through this tree is made through Culture instead of Science. Civics are researched in a Civic tree parallel to the traditional scientific tech tree.Workers have been replaced with Builders that complete their jobs instantly but have a limited number of uses.Happiness is once again calculated for each individual city, and it can be improved through the accumulation of Amenities. City growth is kept in check by Housing metric, which is increased by certain buildings, fresh water, and tile improvements.Wonders are similarly constructed on tiles next to the city rather than within the city itself. Cities now span multiple tiles and can be expanded through the construction of " districts" on adjacent tiles.There is a new game engine with support for a day/night cycle and camera rotation.Information Era The Information Era TechnologiesĢ0px Mechanized Infantry, 20px Launch Moon LandingĢ0px Launch Mars Reactor, 20px Operation Ivy, 20px Build Thermonuclar DeviceĬan be completed multiple times, increasing your points towards the Score Victory.

This bonus is a sort of Quest (such as "Meet another Civilization" or "Build a Quarry") which when completed, will award a research credit worth 50% of the science previously needed to unlock that tech. Most technologies have a " Eureka" objective / bonus. This is not guaranteed, but it's another good reason to search them out and claim them before anybody else does. Players can also obtain technology from some Tribal Villages. Each technology costs a certain amount of science to learn the more science generated each turn the shorter the amount of time it takes to research each technology. Every turn a civilization generates an amount of science that can be used for research. Players acquire technology by accumulating " science," which represent the amount of science a civilization possesses. And technological advances in medicine and sanitation fought off the other great threat to civilization – disease. Technological advances in weaponry and masonry allowed cities to drive off jealous barbarians seeking to steal their food and plunder their wealth. Technological advances in agriculture and fishing caused cities to grow and thrive. Technology is one of the driving forces behind civilization.
