There are Star Metal meteors in the game, that will kill players and npcs as well as damage player built structures.
I think that having some type of environmental damage like this might be a mechanism to help address excessive building by players.
This would also improve the depth of the experience of the game, having something dynamic happening in each Biome.
This could be something like, Iron Meteors in the desert area, Steel Meteors in the Highlands/Jungle, etc.
Of course it doesn’t have to be Meteors in each area, I just thought that since that mechanic was already in the game, it might be easier to adapt to other purposes than inventing new dynamic environmental effects.
