It seems voxels would come in vogue when hardware advanced faster than the resolution people expected to play at. In the mid-1990s, for example, you could get away with dumping players to 320x240 for a spectacular run at Comanche. The voxels and pixels were roughly equivalent in rendered size. But by the turn of the century everyone wanted to run at 768 lines or whatever, where voxels would be slow and have this unpleasantly pointillistic look, like a cloud of little floating dots or blobs.
A lot of modern “voxel” games use voxels to represent data but is rendered conventionally. Such as Minecraft. And often I see a ‘true’ voxel game, they’re going for a nostalgic revival of the glitchy impressionistic look from the 90s.
