Hey guys I wanted to share my idea to see if its any good you can post your ideas to if its not related to mine or you can improve mine or others.
Two types of water and lava one that can flow like a river and the one we already have
Uranium is radioactive and it hurts you when your close to it, it's the right color, You can make a nuclear reactor and if you leave it in there radioactive goo spills out and you can make uranium tools and bombs.(Got idea from uranium mod)
Armor
NPC's can move and interact and you can tell them want to do
Drink's like milk, Pop, beer(makes you dizzy and blurred vision if drink enough), water, and juice
More food like bread, butter, Bread and butter(can make your character fat), ice cream(made with ice and milk)
Freezer and Fridge cooked food and drinks in fridge or it gets spoiled and in freezer raw food and ice cream
New tools like hoes, Hammers for forging on furnaces or make an anvil to forge minerals faster, a spoon to stir liquid and a special crafting place or bowl to add the ingredients and stir to make
plastic to store drinks or glass cups and bowls to eat wheat cereal or soup
Some of these ideas where from videos about ideas or from minecraft itself
