Of these, I'm familiar with Enshrouded. Although I suppose it's voxel based in a sense it's not really voxel-based like minecraft is. Like instead of displaying the voxels as is, the game interpolates them into smooth shapes. Also characters and placables are high-poly like you would expect from any other game rather than blocky like in minecraft.
The effect of this is that it's actually quite non-obvious that it's voxel based unless you pay careful attention.
I don't totally follow how this is relevant to the thread? If you make your own game engine, you can design it to display the voxels however you wish. It seems odd to dismiss Minecraft-like games as unsellable when many Minecraft-like games have sold very well by expanding on the gameplay and visuals. There is no reason why the developer in this article can't do the same.
There's also the fact that the map is fixed rather than procedurally generated, that there is a story with voice acting and plenty of lore scattered. To me the differences are large enough that I don't consider it minecraft-like. But I guess that's a matter of opinion.
