Weather (DUPLICATE, DECLINED) :(
This is a optional idea to spice things up a bit in SE.
If the game had weather on planets such as electric storms on Earth that strike and possibly damage ships, voxels, players, or the electric systems in the ship.
Dust storms on Mars that make it hard to see and push small ships with wind.
And the Alien planet could have very bizarre weather, such as wind storms that dissolve blocks slowly and push ships.
