When you do something really special, like 100% a Godot game, get in the top 1% highscore, Buy Game, Subscribe to a specific studio or something similarly special, you would get a badge.

This badge will be added to your badge collection (which you will be able to find in you profile page) and then you can choose one of them.

The badge you have selected will then be shown together with your username and profile picture in highscore lists and any other place where you are shown.

You would be able to select any of your badges (only one at a time though) at any time but the important thing is that it lets you show the world that you did something special.
