What's the best sandbox?

In my opinion garry's mod is too the best sanbox

my counttry dont have many servers ofsandbox

I don't know if they count as sandbox necessarily (can 2d be sandbox) but Terraria and more recently Noita are pretty fantastic.

They both have an insane amount of potential for terrain customisation, though Noita doesn't let you share the results with anyone.

real life? i dont think sooo :D

the best sandbox is minecraft
