Minecraft Iron makes the game harder by adding features such as stamina, hydration, heat and cold, nutrition, as well as tool and material progression. You'll start with sticks and rocks, you'll need to craft the Crafting Rock for your first tools. There are now Copper and Steel tools, and reaching Iron tier will be more of a proccess. There is also post Iron upgrades and post Netherite tiers.
Iron can only be obtained through Create Iron Sheets or by upgrading Copper gear with an Iron Smithing Template.
Food spoils, animals have to be butchered, trees don't float, torches and campfires extinguish and go out, fire spreads kinda fast, mobs have solid hitboxes, zombies are scarier, when it's dark, it's DARK.
