Is there some kind of sandbox 3d world where you can create buildings and surf them on the Internet?

Question

3D

Give advice. I'm looking for an open 3d world sandbox with the ability to create buildings (and landscapes) that can be shared. Only Minecraft comes to my mind, but somehow everything is very toy... What other projects are there in which you can create in the open world? Not necessarily free. It is important that users can enter and walk on buildings.

Answer 1

SketchUp in the free version is all online, including the editor.

Answer 2

Terraria

Answer 3

Always wanted to do something like this. Like Yandex maps, but with the entrance to the building.

Answer 4

Space Engineers

Answer 5

Minecraft :) There, if you look closely, it’s not a toy at all, but everything is fine like that
