Building not. Try building a nice house, but when you try to place blocks you get a burb of tiny blocks being strewn all over.
... so Vintage Story doesn't exist, and neither does its axis-aligned voxel placement when chiseling?
Terraria is a completely different game
You can still build things in it, I don't see how that's relevant to the topic of 1m blocks being a hard requirement.
Also, for a 2D game, halving the block size means you quadruple the amount of blocks. For a 3D game it’s 8x.
You don't need to divide voxels by powers of two, Terraria and Starbound have roughly 2x3 player hitboxes - which would translate to 2x3x2 hitboxes in 3D spaces.
[...] Or an RTS where units can freely move in 3D
