'Worlds' is a simulator intended to recreate human history all the way from its origins in alternate world settings.

Current features:

• A 2D cell-based terrain generator that creates continent-based worlds with semi-realistic temperature and rainfall patterns. Biomes, like deserts and forests, are assigned to each cell based on its specific climate. 
• An alternate 3D globe visualization of the map with a simulated, cosmetic day/night cycle.
• A map editor that allows you to modify the terrain in multiple ways: Offset the global seal levels, temperatures and global rainfall. Or use a brush to tweaks individual attributes on each cell.
• Humanity starts from a single place on the map, either chosen by you or random, and spreads all over the world, adapting along the way to the diverse environments.
• Populations in different places grow and evolve, diverging socially and technologically over time under the influence of environmental factors and interactions with other cultures.
• Population groups can join and form basic political and territorial entities (polities). Each which might in turn develop its own language and culture.
• Multiple map modes and overlays that will allow you to observe how human groups differ from each other on multiple aspects, from population densities to cultural attributes and technological advancements.
• You can take over polity factions and have some level of influence on events that happen to them.

Planned features (see also roadmap):

• World Generation:
  • Add oceanic current. These will have an effect on climates, fishing and maritime routes.
  • Add drainage basins that will give raise to, rivers, aquifers and associated biomes.
  • Add geological/planetary events: volcanic eruptions, earthquakes, climate change, etc.
  • Add more customizable world generation parameters, templates and modding.
  • Add the ability to import custom world maps and population/polity setups.
  • Add support for bigger/smaller worlds.
• History Simulation:
  • Add more production activities like fishing, herding, crafting.
  • Add cultural values to societies which will influence how different human groups behave, evolve and interact with each other.
  • Add more abstract cultural identification/separation mechanics (art, social customs, sports).
  • Add cults/religions which might expand and influence societies.
  • Add population centers (villages, towns, cities) to which populations will migrate and where more complex production systems (industries) can evolve.
  • Add a more robust agricultural system where different crops can be planted and harvested, and different animals can be domesticated and exploited.
  • Add to polities more complex politics, different forms of government and different social structures (ie. clan systems, caste/class based societies, egalitarian societies).
  • Add diplomatic interactions between polities: conflicts, treaties, alliances, etc.
  • Add trading routes between cities and polities.
  • Add modding for cultural attributes, political systems and events.
• User Interface:
  • Add the ability to zoom into regions/polities.
  • Add more and improved visualization overlays and views.
  • Add data graphs and a history log viewer.
  • Add a 3D globe view.
• Music/SFX:
  • Add basic UI sounds.
  • Add a procedural music generator that creates music tailored to individual cultures.
• User/Player Interactions:
  • Improve a player's ability to take control/influence individual polities.
  • Add the ability to 'time-travel' to arbitrary periods in a world's past without the necessity to load a save.
  • Add an in-engine timelapse viewer/player.
