Set in a near future reshaped by rising seas and climate change, Anno 2070 asks players to build a society on a world where coastal cities have suffered and much land has become inhospitable. Its strategy focus is economic management: colonize islands, grow cities and coordinate the resources needed to sustain them. That environmental premise gives the familiar city-building task a distinctive pressure, since choices also affect the world and the needs of its population.
The work is in the connected systems. Players engineer production chains spanning Robot Factories, Oil Refineries and Diamond Mines, then trade goods and commodities to develop a powerful economy. The game also frames development as a choice between the industrially minded Tycoons and the sustainability-focused Ecos. Decisions affect the environment and the architectural appearance of the world, so expansion is presented not simply as accumulating buildings but as shaping the society that depends on them. Smuggling goods between harbors and forging alliances offer further ways to expand influence.
Anno 2070 is listed with both single-player and multi-player categories, alongside its emphasis on managing a society, resources, diplomacy and trade. The setting, competing development paths and interlocking production and trade systems are the defining context for understanding what kind of game those counts relate to.
