There are quite a lot of successful voxel-based games; see https://voxel.wiki/wiki/projects/ for an incomplete list.

Most people think voxel means 'cube' or 'block', but really it just means "regularly spaced sample in a 3-or-more-D grid".

The voxel gamedev community tends to call Minecraft-y voxel games "bloxel"-based.
