Minecraft, but…
20 original data packs written here at MineSpecs for Java Edition 26.3 — no mods, no loader, just drop the zip into your world’s datapacks folder. Every one is free, self-hosted and released under CC0, so you can take them apart and build on them. Most need 26.3 itself, because that release changed how loot tables and predicates are written; 3 also load on older releases, back to 1.21.x, and each pack’s page says which.
One swing, ten times the payout: every ore drops a tenfold haul, and Fortune still stacks on top.
33 hostile mobs pay out: rewritten loot tables, themed treasure, and no farm exploits.
Every block of stone you break is a lottery ticket. Usually cobblestone. Sometimes a diamond.
Kill anything and keep it forever - every mob drops its own spawn egg, so your kill count becomes a collection.
Every gravel block drops flint. Every single one - and you keep the gravel too.
Punch one tree and walk away with saplings, apples and sticks for a whole new world.
A random item lands in every player's inventory every 30 seconds - dirt, diamonds, or a lit fuse.
Every 45 seconds the dice are rolled for every player: 35 possible status effects, 20 seconds each, no take-backs.
A wide world on a countdown: the border closes in on a timer and never opens back up.
Every hostile mob you kill bolts another half-heart onto your health bar, permanently, all the way up to 40 hearts.
Mobs pay out XP levels instead of orbs, and the scarier the mob, the fatter the payout.
Sleep through the night and wake up to a chest of supplies sitting right beside your bed.
Every villager trade refunds an emerald and XP on the spot, and streaks, jackpots and milestones stack on top.
Junk is deleted, treasure is six times more common, and a Lucky Tide rolls in every five minutes.
Thirty-nine budget recipes for the stuff that always costs too much, with every vanilla recipe left intact.
One egg plus that mob's signature drop equals its spawn egg - 48 recipes, zero spawner hunting.
Every rainstorm turns the sky into an artillery battery, and only clear weather makes it stop.
Every hostile mob that spawns is bigger than the last. Ten growth stages, forty minutes, no way back.
Die anywhere and your gear is packed into a chest on the spot, with the coordinates sent straight to your chat.
Dusk to dawn, open sky is lethal: escalating debuffs stack on anyone outside while every hostile mob gets buffed.
