Quick Answer
Long survival worlds usually run out of repeat materials before diamonds: iron, paper, food, XP, wood, gunpowder, and trade materials. Farm priority should be based on daily use, not on how impressive a tutorial looks.
Material Priority Table
| Material | Source Direction | Use |
|---|---|---|
| Iron | Iron farm, mining | Hoppers, rails, tools, redstone machines |
| Paper | Sugar cane farm | Books, maps, trades, rockets |
| XP | Trading, mobs, smelting, Nether quartz | Mending, enchanting, book combining |
| Food | Crops, animals, villager trades | Exploration and combat sustain |
| Gunpowder | Mob drops, creeper farms | Rockets and explosive materials |
Build Advice
Build small farms that immediately improve the world, then connect high-frequency materials to storage. Avoid giant machines for resources you might need someday; maintenance can slow the entire survival file.
