I've heard that there is a VERY rare chance (due to glitch) that a Nether biome can spawn in the overworld. What if that became a legitimate thing (1/1000), and that in the Nether there is the same small chance that an overworld biome can spawn in the Nether. The biome would spawn normal overworld mobs just like it would in the overworld.
I actually made a map of a nether oasis before I saw this post, or heard of it, it does seem like an interesting concept though, heck, just look at my banner
Like it?
I wish I was in this :C
I don't think you get the logic
I wish I was in this :C
An overworld biome in the nether would have a lot of differences (no day/nigh cycle, no sky etc.)
