Storage capacity grows every year. But let's look at it from another perspective. A triangle requires at least three polygons. We're approaching (tesselation) detail of more than a triangle per pixel (Crysis 2 useless PC Tesselation patch). At this point, storing models with that kind of (non-tesselated) polygon detail requires much more than a single voxel in an octree. You can actually get that voxel data down to one bit on avarage in a sparse voxel octree. That means that voxel data suddenly become much more compact to store.
I just finished Ultimate Doom (all episodes). To me gameplay matters more than graphics, by far. But what I want is a total experience out of game. Doom gives me a whole better experience than Crysis, because it's much more believable.Notice how JC mentions that no matter the detail, the end result is the inspired content. If the game is dull and boring, graphics only prove a shallow wow factor before the fun wears off. I think this is the sole reason for the success of games like fallout new vegas. The game engine is 5 years old but the game itself has oodles of awesome content that made the game what it is, regardless of it's obsolete 3D engine. Same with minecraft, not exactly the best graphics, but the inspired gameplay gets people hooked for months.
Comparing Doom's graphics to Crysis, I find Doom a much better emersive experience. That's because Doom doesn't look like a washed out tattoo, spreaded as a wallpaper over paper-model shape with a custom shiny wax job on top.

It's so much cooler seeing I blast a monster's shoulder of in Doom, than seeing some model drop like a doll with a washed out stain of ketchup in Crysis.
So far what voxels can do that traingle can't. Now the lightning...

I don't know...Speaking of which, what type of storage system is a game like minecraft using? It looks like a voxel octree... It would be good to load up one of those minecraft maps in a voxel editor to play around with the data sets.
