Minecraft 2 ideas

 In Minecraft 2, to make the game more realistic, there will be taxes based on how big your house is.

3x3=300 E

4x4=400 E

5x5=500 E

(E stands for emerald)

Also, most of the mobs you know in Minecraft will be gone and replaced by new, better mobs.

Cow-Ox

Chicken-Eagle

Ender Dragon-Small Enderman

Now, most things in Minecraft are blocks, so they will be replaced with 4D cubes, as people who played Minecraft as kids back in 2010 are now adults. Therefore, the game will have to become more complex. And now if you stay outside too long, you get the plague, which will stay on you forever, even if you die.
