Aren't voxels like not actually 3D? I don't know if it was really as good as they said, you'd think it would have been snapped up by now. That island, with the dirt grains and what have you, that's gonna look good when they add shadows to it, sure they could find a use for that level of detail. Someone showed me a game on steam that was literally you as an old woman wondering arond a graveyard, sitting down, and being all old, I'd like to walk around a level without a polygon evident in sight.

I know this game as someone spammed me with it using the gift option. Thankfully ignore gift works now rather than seeing it everytime I opened steam.
