First, let’s clarify what this is about. If you purchase the "RimWorld Name in Game Access" DLC, you gain the ability to add your character’s first and last name to the game. This character may then appear for any RimWorld player.

Here’s a brief guide on how to add your character:

1.Purchase the DLC.
2. Log in to the official website:
https://rimworldgame.com/creative/index.php/creation
3. Submit your request.
You can also check whether your submission has been approved on the same website.

To verify if your name has been added to the game:

1. Locate the file containing player names:
...RimWorld\RimWorldWin64_Data\resources.assets
2. Open it using Notepad++. The file may start with strange symbols, but that’s normal—just scroll to the middle, where you’ll find the name list.
3. Press Ctrl+F and search for your character’s first or last name.

Some guides recommend other programs, but Notepad++ is lightweight and widely used.
