Will It Host?

Yes. The process listening on port 25565 is OUTLOOK.EXE, and you start the server by emailing yourself the word START. A vanilla Minecraft client connects to it and plays on it. This was the hardest build in the series so far.

Yes. The process listening on port 25565 is EXCEL.EXE, and a vanilla Minecraft client connects to it and plays on it. This was the first build in the series, and the protocol code written for it went on to run three more.

Yes. The process listening on port 25565 is WINWORD.EXE, and a vanilla Minecraft client connects to it and plays on it. The world is drawn on the page as an isometric render, and every block you place or break lands in the margin as a tracked change, so by the end the document is an edit history of a Minecraft session.

Yes. The process listening on port 25565 is POWERPNT.EXE, and a vanilla Minecraft client connects to it and plays on it. Slide 2 is a live isometric render of the world built out of cube autoshapes, and the deck moves itself to that slide when you connect and back to the title when you leave.

Yes. The process listening on port 25565 is an app on the phone, with no Mac in the middle and no jailbreak. Press Start and the phone answers Minecraft. The server list entry reads the model, the iOS version and the battery level off the device, so from the multiplayer menu you can watch the phone's battery drop. Getting a client to reach it at all took far longer than the protocol did, and in the end the connection ran over a VPN.

Yes. The process listening on port 25565 is FL Studio, and a vanilla Minecraft client connects to it and plays on it. The world is the sequencer: build a wall in Minecraft and FL Studio plays it, locked to the project tempo, so placing a block while the transport runs puts a new note in the next bar.

Yes. The process listening on port 25565 is The Sims 4, and a vanilla Minecraft client connects to it and plays on it. This is the first one that goes both ways: place a block in Minecraft and an object appears on the lot, move furniture in The Sims and the block moves in Minecraft.

Yes. The process listening on port 25565 is Garry's Mod, and a vanilla Minecraft client connects to it and plays on it. This is the first host with physics: every block placed is a real prop, so you can physgun it, drop it, shoot it or blow it up, and the block does the same thing in Minecraft as it happens. The Minecraft player is a ragdoll you can pick up and carry.

Yes. The process listening on port 25565 is Blender, and a vanilla Minecraft client connects to it and plays on it. This was the first one that renders the world instead of reporting on it: the terrain is real geometry, you are an object that moves, and the scene camera takes its yaw and pitch from your movement packets.

Yes. The process listening on port 25565 is VLC, and a vanilla Minecraft client connects to it and plays on it. This is the one where the host reacts: play a video, connect, and turning your head rotates the hue, looking up and down changes the brightness, and walking away from spawn oversaturates the picture.

Yes. The process listening on port 25565 is Resolve, and a vanilla Minecraft client connects to it and plays on it. No plugin, no compiler and no mod loader: Resolve ships a Python console running inside its own process, and that interpreter has sockets. The world becomes the edit, with a live top-down map in the Fusion viewer and a coloured timeline marker for every block placed.

Yes. The process listening on port 25565 is Firefox, with no extension, no mod and no recompile. A tab opens showing the world as a live web page, every player who joins gets their own tab, and every block placed becomes a bookmark on the toolbar pointing at that block's wiki page.

Yes. The process listening on port 25565 is Terraria, and a vanilla Minecraft client connects to it and plays on it. It runs both ways: place a block in Minecraft and a tile appears in Terraria at the matching spot, mine a tile in Terraria and the block disappears in Minecraft. Two worlds, one 3D and one 2D, editing each other in real time.

Yes. The process listening on port 25565 is the Unity Editor, and a vanilla Minecraft client connects to it and plays on it. The world is the scene: place a block and a cube appears in the Hierarchy, delete the cube or drag it with the move gizmo and the block follows, and Collapse World switches gravity on so the whole build falls down in both at once.

Yes. A Python script inside OBS speaks the Minecraft protocol over a socket, and a vanilla client connects to it and plays. The software recording the episode is also the server in it.

Yes. The process listening on port 25565 is Code, and a vanilla Minecraft client connects to it and plays on it. The world is a file. Place a block and a line writes itself, delete a line and the block vanishes, which turns every editor feature you already have into a world editing tool, because all of them are just text edits.

Yes. A real TCP server runs inside Obsidian's own process and a vanilla Minecraft client connects to it and plays, while the notes app writes the server's own status into a note as you go.

Not inside it. Google Earth cannot run code, so this is the one episode where the application is not the process on port 25565. The server is a standalone Go binary and Google Earth is its second client: every block you place lands on the real planet at the coordinates you are standing on, and Earth draws it within two seconds.
