Pet Rock 2 is an exoplanet creation/simulation game based on real planetary science.
You begin with a simple rock in space. Choose your star type, adjust the parameters of your planet's orbit, chemical makeup, and bombard it with meteors. Watch your planet grow and change--and if the conditions are right, watch as it develops life. Make a gas giant with a crushing atmosphere and a dozen moons, a tidally-locked ice planet, or a densely populated terrestrial world... it's all up to you!
