Dude, I look at old 3d DOS games, and the graphics were so great for the time. Ok, nothing like we have now, and you were lucky to play in 640x480, but with Voxol terrains and all that good stuff, things looked awesome. Blocky but awesome. I mean, look at the first 3d Windows games... It was almost a downgrade. Sure you got cleaner edges and more actual 3d stuff, but it looked crappy. 3d modeled terrains started out with sharp edges and tiling textures, voxol terrains were smoothe and round I.E. Commanche 3d and Terra Nova. No, I'm not saying the old tech was better, but it sure ran faster than polygons...
