Really Really Really Tall Building

[Omegagoldfish]

You rip the thing off of your back. It's floor 1432. You enter it and see a giant iron ball.

[Matuchkin]

Floor 1433. Pewdiepie, Winston Churchill, and Richard Lionheart, in modern formal clothing, seem to be having an important meeting. The moment you open the door, they turn their heads towards you.

"Ah, we've been waiting for you", says Pewdiepie.

"Please sit down", ads Churchill.

[Andem]

Leonardo DiCaprio runs in and guns down the three men. He turns to you and yells for you to hurry up. You rush up to floor 1434, hyperventilating. You see your cousin Steve and your uncle Frank. They stare at you blankly until you proceed to the next floor.

[0111narwhalz]

Floor 1435 sees you in a crumpled heap, passed out thanks to your aforementioned hyperventilation. You regain consciousness,wondering why DiCaprio shot Churchill and Lionheart, and who the hell Frank and Steve are.
As you get up slowly, moving for the staircase, the building wonders why you didn't think twice about the internet sensation's assassination, and begins judging you silently.

[Matuchkin]

You open the door to floor 1436, and bump into Stephen Hawking, who twitches his face in slight annoyance as he tries to shimmy by you in his wheelchair.

"Excuse me", his computerized voice asks, "do you know the direction to the washroom?"

[AlmostNASA]

Floor 1437, it seems straight forward but it is an illusion then you walk for miles and you find the Glade in the Maze Runner

[Omegagoldfish]

Thankfully you didn't watch that movie, so it vanishes and you walk to Floor 1438. Which is covered in landmines.

[njmksr]

BOOM! Your crippled torso is blown up the stairs to the next floor, 1439.

On the next floor, a featureless, hovering grey sphere glows blue.

"Long time no see, David. Let's get you back on your feet."

It heals you, but your name isn't David.

"I gotta say, next time, don't keep me waiting this long. It's been [ERROR_BUFFER_OVERFLOW] years."

"I'm sorry, I don't know you," you say.

"Surely you remember your old pal M1-κε? You called me Mike, if you remember."

You go up the staircase, with Mike humming a tune you don't recognize and following you up.

"I'm with you now. Let's get out of here."

On floor 1440, M1K3 is disintegrated by a particle emancipation grid.. A woman's voice, severely digitized, comes over the microphone: Unfortunately, cooperation and the dynamics of social interaction with a seeming stranger are not part of this test. Alter the testing environment further, and you will receive an unsatisfactory mark on your testing score, your party will be cancelled, and you will not receive any cake! You roll your eyes and proceed to the next floor.

Stenciled upon the wall opposite to the stairwell are the numerals 1441. As you look down the hallway, you note a floating orb, apparently suspended by arcs of lightning, slowly making its way towards you. A menacing hum fills the air. One of the orb's arcs flashes remarkably near you.
Since you really don't want to get electrocuted today, you jink down the hallway into another, upwards-bound stairwell.

Floor 1442 hosts a single F1 engine pointed downwards in the center, and in one corner lies a charred pile of ashes with a sheet of notebook paper on top, on which the words "Did not go to space today" are written. 

[ZentroCatson]

Floor 1443: This floor is a massive donkey pen. The monotone screaming of the donkeys gives you headaches, so you quickly run to the next floor.

[TopHeavy11]

1444: Overwatch. You run for your sanity.

[Andem]

1445: Undertale. You run for your sanity.

[Matuchkin]

1445: Overtale. Sanity runs after you.

1446: Metatale: Sanity runs after you run after sanity runs after you run after sanity runs after you run after sanity runs after you run after sanity runs after you run after sanity runs after you run after sanity runs after you run after sanity runs after you run after sanity runs after you run after sanity runs after you run after sanity runs after you run after sanity runs after you run after sanity runs after you run after ...

1447: You meet Jared Leto. You proceed.

[ZentroCatson]

1448: Subnautica. You spend an evening enjoying the game.

[icantmakemodels]

1449: A team of highly trained monkeys is furiously typing away.

[Matuchkin]

You jostle through the monkeys, and head towards floor 1450. You get blocked by a pop-up message that says you need to install the latest version of Adobe Flash Player to view that content. Dammit, guess you're stuck here for now.

[njmksr]

You install flash and proceed to 1451, and you say hi to Roswell.

[Matuchkin]

Floor 1452 is a room.

Just a blank empty room, the size of a closet.

You try the door behind you, but the door is replaced with a blank wall.

[ZentroCatson]

You notice a rope dangling from the ceiling and climb up.

1453: This room is filled with various fuel tanks containing fuels that were used, are being used, and will be used.

[Firemetal]

You see an engine on one of the fuel tanks: You light it and blast through the ceiling.

Room 1454: This room is filled with candy, So much that you cannot see an exit.

Floor 1455:

It's an empty room apart from the short, box-shaped robot on the charging platform.

It wakes up, displaying a smiling face on its screen, and chirps excitedly as it begins following you around while making cute noises.

1456: This floor contains the magic wall that shields the KSP forum from the rest of the internet. This explains why the KSP forum is such a friendly place.
