Synapse

Synapse: Chronicles of Chaos casts you as a Temporal Architect who must steer humanity from Antiquity to the Future without letting Chaos win. Each turn three cards are offered and only one is played, and each one writes, or undoes, a piece of history.

Balance Stability, Progress and Chaos, and meet each era's quota of its major tag before you can move on. The World Tension follows what other players chose over the last few days, so a card that was harmless yesterday can be devastating today. Free in the browser, in English and French; still in development.
