World two:Minecraft

Duration in the world: one year-or until the ender dragon is killed.

World bonus: The inventory of a Minecraft character.

How it will work: The MC is the only person in which Minecraft physics doesn't apply to. Meaning that a bite from a cave spider won't stop before you die it would kill you. Wounds don't simply regenerate by eating food, no punching trees, no magical crafting powers, and more. Magic potions still work as intended in fact they work far better in this world than the game, same with ender pearls.

Mobs: For the most part Mobs are the same. Except for the fact that they all are much stronger and far more brutal and actively search out not only the MC's but any villagers and things that aren't them deaths too, who by the way actually talk and have hands. Also a zombie bite will leave an infection(not the zombie kind.)

About the resident's: There are actually a few kingdoms in this version of Minecraft. One being the villager kingdom, another the illager, and finally the player faction( which only has a few thousand people since they are so powerful).

About the End Dragon: The end dragon is far far more powerful in this version. There isn't going to be a way for the MC to one v one this thing (unless you gave him very powerful abilities).

About Steve: Steve is the MC of Minecraft along with Alice so there should be quite a few interactions with them.

Ps: Everything is no longer blocky when the MC get's there.
