1- Haunted Forest Biome- Dark trees that introduce new mob, Haunted Tree. It has basically the same features of an enderman, It comes to life when you look at it and a Jack-o-Lantern face appears and it chases you but can't follow when your looking at it. It would also be pretty rare like the mushroom biome.


2-Volcano Biome- This would be centered around a volcano with things dotting the surroundings like burnt down trees, lava pools, piles of ash, etc.


3- Natural Disaster- This would include tornados,hurricanes,earthquakes,mudslides,tsunamis, volcanic eruptions, and sandstorms. There would also be things that spawn with the world like pitfall, place of earth that fall when you step on them. It would be like cracked dirt or something. Also quicksand.


4- More Methods of Travel- This would be like horses,airships,wagons,carriages,larger boats that arn't just rowboats and anything else you can think of.


5- More than just the Testificates- I mean how cool would it be to stumble upon a village of centaurs, goblins, trolls, elves, gnomes, dwarves, minotaurs, orcs, merpeople (this would be in the ocean though), or maybe yetis or something. The possibilites are endless.


6- Graveyard Biome- This would be a graveyard thats randomly place maybe like 10 a world. There would be ghost/ghasts/banshees that come out at night for you to fight. Maybe you could find chests underground by graves with treasure in it. And in the middle there would be a crypt (Basically a mini-stronghold) that you could enter and fight through.


7- Side Choosing- There would be a few countries who each have different specialties. Your actions and stuff would help determine which side or you could remain neutral. This would also affect what happens when you enter villages, depending on whats in it, it would welcome you, not do anything, or attack,


8- A game mode where you are spawned in a village and have to defend it. After defending you explore and if you find new village (there will be a lot more spawning in this mode) you can add it to your empire. Each village will need defenses to be added to your empire. The mode would be called "Empire" or something. There might also be enemy empires.
