Voxels are just the 3d analogue of pixels. No textures or high detail required!

I think this one counts - look at the aliasing on the player's avatar's turret, and the rotating coins.

The Amontage Engine would probably qualify as a volume renderer in original terminology.

This is kind of a 'no true scotsman' argument right? In Voxelvoid, I resample the 3D models to a grid in real time.
