Looking to see the difference between the two technologies in a game experience and not in experiments - is there a half-decent game out there that has two modes - polygons and voxel?
EDIT
Games like minecraft that voxels are exaggerated to make the game appear like a retro is not the intention. The comparison I want to make is for games that attempted to deliver realistic experience like outcast. In addition it would be best to see the same assets in both versions so not characters in polygons and landscape in voxels.
