Hello, I'm glad you made this post!
As 1.16 is still relatively new, hype for the nether has never been higher except when it was created. Nether only survivals have been extremely popular on YouTube - but there are no perfect data packs for the best experience.
I propose you make the perfect version (Nether only survival)! People like survival packs the best as you can have extensive customized playthroughs. This is what I think it would include:
- Spawn in nether with nothing but a respawn anchor and 4 flowstone, perhaps with 30s of fire resistance in case of bad spawn.
- Standing anywhere in daylight or nightlight in the overworld would cause you to be on fire. Water would cause small damage and slowness. This is to encourage a true "nether only" survival, but NOT MAKING IT IMPOSSIBLE to go to the overworld. You can get fire resistance potions from the nether, so your time there would be severely limited!
- Remove all achievements that would be almost impossible (such as certain adventuring and husbandry ones, as limited overworld time would be in the playthrough
- The end portal would either be in the overworld normally OR you could make it custom, being somewhere in the nether. It would warp you to the roof of the nether, where the end battle would take place.
- New achievements?
