So you installed Minetest Game, the modding base, with no mods and are mad it’s not Minecraft, got it. Minetest Game isn’t about cloning MC, it’s about building your own game out of mods. If you want a Minecraft clone, that’s what Voxelforge and Mineclonia are for.

Personally I couldn’t care less – I don’t like Minecraft (and am not a big fan of Minetest Game either) and am far more interested in original voxel games that are not joined at the hip to bad design decisions made by Notch and/or Microsoft just because Minecraft did it. (Looking at you, crafting grid)
