nothing hammers home my 'minecraft is the game of a million sidequests' belief more than my repeated "Collect Every Item in 100 Days" challenge runs that I love doing.
Because I guarantee you, I get diamond gear and full diamond armor by day FOUR, usually have the dragon dead by day eight and have already got my elytra up and off to the races by day TEN. Progression sorted, grab my max enchanted gear from the end cities, use the dragon levels to enchant what I didn't get (Looting and Fortune are must-haves), and then the real fun begins.
Because what side quests do I have to prioritize to truly get every item in Minecraft?
Fly to every biome and collect every wood type
Drag home armadillos, frogs, and goats for their respective drops
Create a little minecart hopper contraption to hatch turtle eggs + grab their scutes, and later to collect sniffer plants
Find and loot Ancient Cities
Run through Trial Chambers and Ominous Trial Chambers
Loot Shipwrecks, Ocean Ruins, and Buried Treasure for 2 Diamond Nautilus Armor
Find different biomes for their unique materials, such as Badlands for red sand & terracotta, Swamps for blue orchids, Coral Reefs for all 15 types of coral + sea pickles, and basically something new for every biome
Loot other structures like Desert Temples, Jungle Temples, Ocean Monuments, Woodland Mansions, Pillager Outposts, Desert Wells, and more for all their unique items.
Trade with villagers for the globe banner pattern, chainmail armor, and all the cartographer maps (and maybe snag a mending villager for my elytra if I didnt find a book earlier)
wait for a thunderstorm to get charged creepers for mob heads
literally dozens more things
that's not to say that there's nothing to be added to change or at least effect the "core gameplay loop", like adding Bundles for increased storage capacity (godsend for this challenge), Copper Armor to slightly buff up you in your first nights if you need it, Spears to provide an alternative melee weapon. But you'll notice that all of those things were added in drops - Recent Drops. MOJANG FUCKING DOES THE THING YOU WANT WHAT MORE COULD YOU ASK FOR YOU INSANE SONSA BITCHES!!
