Not a real game but a simple simulation of gravity in a solar system. Creates a number of random planets around a sun. Their number will decrease over time - they will collide, merge or fall into the sun. But in the end some will find a more or less stable orbit. I love watching it : )

Run the game to start the simulation. You can also adjust the camera:

  • Arrow keys to pan

  • LeftClick and drag to rotate

  • NumPlus/-Minus or PageUp/-Down to zoom

The code is in and should be very easy to adjust if you're familiar with Python.

Cheers, have fun!

    Thanks RedFrost! Of course I did : ) In the end it's only 3 simple formulas I got from Wikipedia wrapped in BGE basics ...
