The CubeWorld Mod adds a neat dynamic to world creation in Minecraft. It essentially separates many different biomes into floating cube planets in the sky.
You start off in one of the cubes based on random selection as always with new worlds. The only difference is you’re encased in glass looking out to all the other adjacent mini cube worlds.
What makes this mod so interesting is how restricting it makes everything. You now have to be a little more creative and resourceful if you want to survive. All mobs will spawn as normal so due to the restricted space, you’ll need to be sure to build shelter lest you end up cornered by zombies or blown up by creepers.
And with that there are also Stronghold and Dungeon cubes that you can build yourself a path to and hopefully reclaim some much needed resources.
This mod also retains the Nether and the End as achievable realms to add even more difficulty to your game.
