A game that has similar building (albeit less "scriptable" since there's no redstone) is Enshrouded. They use smaller voxels and a different polygonisation algorithm (seems to also differ based on voxel material tool). It's a really fun game, even if there's less variety than Minecraft. Also it's still in early access. I recommend you check it out if you enjoy building in Minecraft
