Justin Crafter was an ordinary kid. He went to school and he did GCSEs (even though he was only in year 9, because he's super brainy) and basically other normal stuff... also he was a huge fan of the hit game Minecraft. When he got home, he would go on Minecraft and build all sorts of cool stuff on Minecraft. He also had a popular youtube channel, where he made 'Let's Plays' of the game.
But today was different. When he looked at his computer, the screen was swirling and purple. It looked like... a nether portal! Before he could do anything, he got sucked into the computer and then everything went all black.
When he woke up, he was beside a lake. "It's strange," thought Justin Crafter, "the water looks... blocky!"
He turned around rapidly. All around him – a world made of blocks.
He was in the land of Minecraftia!
This meant that he knew what he had to do: punch trees, mine for diamonds (the rarest thing in Minecraft), and defeat the Enderdragon. He was the player, the player was him.
Justin walked over to a tree. Slowly, not wanting to hurt his blocky hand, he moved his fist towards the tree, and where they contacted cracks spread out. He did it again, and again, and soon the block turned tiny with a pop sound. He picked it up, and stored it in his inventory.
His inventory was strange. Rather than being anything physical, like perhaps a backpack, it seemed to be purely mental, appearing as something more real than his mind's eye but still not part of this reality. As he opened it, a strange feeling enveloped his mind: no doubt the inventory's work. With some thought, he could rearrange the items in his inventory.
He moved the block of wood into his hotbar, and held it in his hand. On the first try, he dropped it out of surprise when it appeared in his hand, but when he picked it up and tried again he managed to keep hold of it.
Experimentally, he pulled the wood up to the crafting area. There, he applied some mental pressure to convert it into planks, and felt it split into four blocks of planks. He recombined them into a proper crafting table. He decided to call the mental process mind-crafting, which he hoped to be able to avoid because the crafting space was only 2×2 and it was rather tiring to do.
Justin, seeing the mysterious hovering remains of the tree, placed the table in place of the block he mined out (it was at the base of the tree), then continued mining out the rest of the tree up to the top of it. The same feeling that filled his brain when he opened his inventory was felt again. He watched as the leaf blocks slowly dissolved, and tried unsuccessfully to grasp some of the falling saplings. Once they were on the ground, he picked them up. He also picked up an apple.
Wondering what other gaming abstractions he could access mentally, Justin thought towards the achievements, and saw the familiar tree. He had achieved "Taking Inventory" and "Getting Wood". Suddenly, Justin realised what had enveloped his mind. "It was the achievements notification!" he said out loud. Only the mobs could hear him, anyway.
Briefly, he wondered why he didn't get the crafting table achievement ("Benchmarking", he found the name was when he checked), before realising that he had mined out a block of wood before opening his inventory, and placed the crafting table before mining out the second block of wood, so he hadn't unlocked the achievement.
"Drat," he said, before continuing to mine out the next tree. He would need shelter, ere the creepers grow combustible.
