Since the nether is getting an update and is going to become slightly more livable, I think we should have this new challenge where you start survival in the nether and then eventually get to the overworld.
And here is a brief description of the progression path told in a sort of story form.
So you spawn in the nether. Everything is hostile and dangerous. No food, no weapons, no armor.
You manage to find a netherwart forest and punch a netherwart "tree" and get its "wood". But it crafts a very shoddy crafting table that can only craft very basic tools before it breaks.
Crafting table broke, but now you have some tools and a sword! Try taking on the Hoglin Beasts. Because you need to eat. They will also drop leather, allowing you to soon make your first suit of armor.
You're exploring the Nether. Better equipt than you were when you started, but you're still looking over your shoulder.
You can find two different types of structures that are both abandoned, allowing you to loot them safely.
Abandoned Piglin Camp
Abandoned Nether Outpost
You can find Gold or Coal, Golden tools or Stone. But you might also find the most valuable item you can get at this point, a bowl. Which will allow you to forage mushrooms instead of hunting everytime you need to eat.
You've looted a bunch of those small abandoned structures. And you have enough gold to craft golden armor. Better than leather, and you can now unlock bartering with piglins.
They'll take things like...
And give you things like...
And you'll need the best equipment to brave the nether fortress!
You've made it to the nether fortress. It's brutal but thats mostly because you're using golden tools and armor.
Piglins in the fortress aren't going to like the fact that you're stealing the flint and steel from the chests.
The goal is to make it through the blazes, wither skeletons, and angry piglins to find the flint and steel, and then find and light the nether portal found somewhere in the fortress.
Light it and go through.
Welcome to the overworld. Its a beautiful peaceful morning. You wouldn't realize it until now but the portal in the nether fortress was special. Once you reach the overworld, the portal you came out of will destroy itself so nothing can get through.
But after an experience like that, you'd probably not want to go back for a while. You went through actual hell and you made it here though. And with your nearly broke golden suit, you are back to humble beginnings, ready to take on a new adventure.
The original adventure.
I think this is the kind of challenge that veterans of this game would love. Survival mode has had this problem for quite a while that there is so little challenge that it shouldn't even be called survival mode anymore.
But it's too far gone. Mojang would have to nerf too many things to bring the challenge back to survival mode. So how about we make a new survival?
In a place that is already a challenge for everyone at any level!
