MineClone5 is a fork of MineClone2, but both are popular and in active development, and because they're GPLed they can freely gank features from each other. They just have slightly different development priorities.
I think even the base Minetest Game is pretty Minecraft-like, though. Out of the box it doesn't have mobs, the Nether, portals, magic, or redstone, but you can add those a la carte to Minetest Game as mods, and there's a cooler redstone alternative called mesecons. You can see the mods at https://content.minetest.net/packages/?type=mod; most of them are applicable to Minetest Game. And in Minetest Game you can mine a lot deeper than in Minecraft. (You kind of have to, which might be better or worse.)
