Do you find vanilla Minecraft to easy? Frustratingly barren even? I have good news for you then.
Welcome to Nicecraft - Sixty-Nine! (because it has 69 mods, get it?)

The idea of this modpack is to make vanilla feel fresh and more challenging again but still keeping its spirit intact. It's supposed to feel like playing Minecraft for the first time again.

I'd best describe it as a "What i want vanilla to be like if updates weren't such nothingburgers nowadays" type of modpack, or "WIWVTBLIUWSNN" for short. (hehe)

Those looking for automation, machines, quests, etc. should look elsewhere though, as i haven't included a single one of such mods. (because it's meant to be vanilla-like)
Bloat is also kept at an absolute minimum thanks to the 69 (nice) mods limit i've kept to myself.

It's a great way to ease friends (or in my case my brother) into modded Minecraft, who may not know much or anything about Minecraft mods. It's all simple & easy to understand and you're never required to look up a wiki to understand what a mod or item can do or how to do something. It's still Minecraft through and through, but with more content and some changes in the recipes, item properties, mob behaviors, etc. to make it more difficult and rewarding to play.

Even though the mod selection is fairly small, i did spend a most of the time tinkering each and every component of the included mods here and i made sure to integrate a good bit of the modded items into loot tables & trade pools, make changes & rebalances where i see fit, and nullified (hopefully) all duplicate items as best as i could to make the pack feel more cohesive and less lazily thrown together.

The main attractions are:

Majrusz's Progressive Difficulty (makes the game harder depending on how far you've progressed in your world and adds new endgame gear)
Biome Makeover (overhauls Dark Forests, Badlands and Swamps, also new Woodland Mansion)
Champions (Gives mobs special perks and makes them stronger, they drop valuable loot if killed)
Bosses of Mass Destruction (new bosses with unique loot and items to secure your base or make your life easier, found in structures that can be located with certain items)
Mowzies Mobs (another mod that adds more new bosses, but also a few smaller mobs & equipment)
Artifacts (like accessoires from Terraria that give passive benefits to the player when worn)
A bunch of structure mods such as When Dungeons Arise, Subterrestrial, It Takes A Pillage, YUNG's Better Minecraft Structures Collection.
Mining Master (adds many elemental themed gemstones for easier enchanting and lets you obtain new exclusive enchantments from said gemstones that can't be obtained via books or enchanting tables)
Quark + Oddities (bunch of small things thrown together, it's best to look up the mod's wiki on Curseforge. Most stuff is enabled unless it's something dumb like Matrix Enchanting)
End Remastered (prevents rushing to the End dimension by requiring 12 from 16 unique eyes that can only be found in structures across both the overworld and nether, vanilla ender eyes will now only lead you to the stronghold)
BetterEnd (overhauls the end to not be a boring wasteland similar to how Mojang made the 1.16 Nether Update. All equipment related recipes have been simplified to use crafting table and smithing table exclusively, so no more crafting components via the anvil shenanigans!)
Custom Villager Trades (Rebalanced and nerfed some trades across the board, they are still very helpful, even somewhat required to reach the end, but are nowhere near as broken as they are in vanilla)
Prolonged Progression (It now goes like this: Wood/Stone > Copper/Gold > Iron/Bronze > Diamond/Terminite > Netherite/Ultima > Aeternium/Enderium. Each tier has at least 2 whole sets and every tool & armor requires whole blocks to craft now instead of only using the ingots, thus a pickaxe or axe will need 27 of the material and a whole armor set a whopping 216! For smithing related stuff it's limited to a single block, so 9 items total.
Bigger Stacks (If there's one thing i hate about vanilla it's the miniscule inventory space! But say no more, the stack size has been increased to 999 for most blocks & items! (With food being 99 and potions at 9 per stack.
Mending rework (Reparing your equipment is a crucial part of Nicecraft. Mending now only serves as a mere QoL enchantment that makes the process of repairing easier by not requiring an anvil, it simply lets you repair your items in the inventory crafting grid and put both the tool/armor and its required repair material. Otherwise you have to use an anvil (removed the cumulative exp cost) to repair your equipment.
Property Modifer (Very important mod that allowed me to change & rebalance pretty much all tools and armors. I gave all equipment a 2-4x bump in durability to compensate for more expensive crafting recipes.
My Custom Datapack where i rebalanced ALL structure loot tables as well as some block and mob drops. (1,015 files according to windows)

Some noteworthy advice to get started:

To mine iron you need copper tools, copper ore can be mined with wood and stone tools.
You can fell whole trees if you sneak while mining the lowest wood log of the tree
All equipment now requires whole blocks of the ore craft, e.g. a pickaxe now needs 27 ingots or a full armor set a whopping 216! However repairing still uses only the ingots or gems to make it not as expensive.
Beds require cloth in addition to wool and planks, you can get cloth from undeads wearing tattered armor. You need to put the tattered armor into a crafting table to get 1 piece of cloth. You cannot steal beds from villages or other structures, as they now only drop 3 wool, therefore requiring the acquisition of cloth. You can still sleep in them as much as you like as long as you don't break them.
Maxed out leatherworker villagers will sell you bundles. (a helpful tool to store more items)
Bronze is a great early/mid game tool set, but to get them you need golden tools as a base, a block of bronze and a bronze upgrade smithing template which can be found in most structures.
You should really think twice about going to the nether early (seriously, you will regret it if you do)

Needs a minimum of 4GB RAM to run, but 5GB is preferable. I believe an 8GB system should be able to play it without much issues regardless. Though if you have 16GB i do recommend allocating 6GB, as some of the huge structures tend to eat away at RAM quite substantially compared to just walking around a flat land.

Performance is 50-100fps on an i3 12100 with Intel UHD 730, 300-700fps on a Ryzen 5600X and 700-1200fps with a Ryzen 7800X3D. All systems have been tested at highest graphics settings and 16 chunks. Server performance stays at a relatively stable 20 TPS (15-30ms latency) across all tested devices but can drop very slightly when generating many new chunks too quickly. It shouldn't be noticable though.

Anyway have fun and feel free to let me know what you think!
