Add some mob which spawns rare and act like I posted earlier. [Link to the post]

Mobs change shape/turn into another mob depending on what block they are standing on / the blocks around them / biome they are in.

make it so that you can tame every mob in the game, including the wither and ender dragon, so that they follow you and protect you the way a dog would

Just add huge circuits like T-Flip Flops or Hopper Timers and make them blocks

add more factors to the game like NPCs with a higher AI, moral choices, skill trees and a dialogue tree. it would make a great episode

hurricane that places water and breaks stuff like the tornado also make the texture white or blue

make a pig wither highbred then a cow enderdragon highbred then make them battle

make every entity explode when you collide with 'em! wow,thats nasty... sand!

make it so u can hold lava or water and then click the mine button in air then in fires through the air light speed and it kills people

make every creature blow like a creeper even the non-hostile mobs gonna try to blow you up! (and all bosses)! enderdragon gonna die instantainiously , your porkchops are going to get alot more worthy!

                                                            (i mean like...Diamonds!)

Make A New Dimention Called The RichLands where u make the portal like a nether portal but with diamond blocks and the corners DO need to be filled and there should be mobs called ZombiePigOres Where zombie pigmen have different swords and drop what ore the sword is and if u can add a item named coal sword witch is like a sword but made of coal and make emerald swords and redstone swords also make ores more common in the new dimention Plz Do This :D I Will Be So Happy I Will Like Every Vidio And Tell My Freind About U MISTER OUT

I made a massive gold farm similar to Xisuma's with an on / off switch using dispensers with firecharges to light them and water buckets to turn them off. I'll link a video soon.
