Summary
As the most ambitious and expansive title in Maxis' Sim series, Sim Earth places you in control of an entire world as it evolves over the course of 10 billion years. Your ultimate goal is to lead the planet's life forms from their simplest beginnings as single-celled organisms all the way to interstellar exploration.
Among the major challenges you'll encounter are pollution, disease, food shortages, conflict, and climate change. At your disposal are powerful tools that allow you to shift mountains and continents, generate new species, and trigger tidal waves and earthquakes to reshape the planet's surface. However, all of these actions consume your limited energy supply, which you must carefully manage and restore.
