Here are some Simulations you can use for your game to play around with:
-Atom (moons orbiting a planet in a Atom-shape form)
-Earth with rainbow ring
-Mini-solar.system V1 (a tiny "solar system")
-Earth with planets as moons (our planets orbiting a giant earth)
How to install (windows):
1. Go to your "documents" folder
2. Now open the "Universe Sandbox²" folder
3. Drag and drop the .ubox folder into the "simulations" folder
4. Have fun!
(the object should be located under "my sims" when you try to open a simulation)
If you have intresting objects or simulations, feel free to message me the linked file and I will maybe post it in the text part with your name as the author
