PlanetFriend

"PlanetFriend is a desktop planet pet simulation game where you can nurture your own planet, affecting its growth and development. The game features unique elements such as a beam weapon to make the planet 'more horny', four types of devastating wars, mass ascension of virtuous souls, arcologies, and very large, strange, rare trees. Modding is encouraged, allowing players to change the game's art and scripting, potentially automating events such as a worldwide rapture."
