I enjoy classic Minecraft worldgen. The fog, the shape of the mountains, the topography. I cant describe it but i enjoy it alot. The sparseness of content (usually trees) makes it almost feel dreamy. Modern mineman has too much detail i guess. They are trying to do too much with the block "resolution" they have. Mountains look strange with all the layering, textures look too detailed/ like usermade texturepack. The terrain is obscured with grass and the an excess of block layers trying to denote slight changes in altitude. It least that's how it feels to me
