Im watching a tutorial the unreal engine... But there is Unity as well ofcourse...

I'm completely new at the idea if game development...

Basically I just want to make a 3d sandbox where I can put dolmens in and things like stonehenge, but also things like platonic solids... and play with night and day / solar and lunar positions lol...

So a sky like in stellarium xD - a real sky, with real lighting...

To for example have a dolmen on the grid with lat. and long. and check equinoxes, solstices & lunar standstills in real time from a 3d first or third person perspective - where I can walk arround it lol.... and zoom out to aerial view to see how the different local dolmens connect xD... and what their astronomical connection is 🤣🤘

So... lol in which one would it be easiest to build 3d structures in a grid & apply some textures?

so I want a real equatorial grid lol... a real night sky - so lattitude and longitudes would correspond with the actual sky xD

Stellarium 3D sandbox creative mode basically 😆

Unity or Unreal? or something completely different?

and ohyeah - I also want to be able to draw euclidean geometry on the ground lol... ruler, compass, and a rope where i can add and remove knots 👌

Thank you ☺️☕
