One of the main hobbies that I have is playing the table top role playing game known as dungeons and dragons. It is a bit of a struggle to try to explain it so instead watch this playlist to learn how to play if you are interested. basically it is a game that you play with friends in which you take the role of a character you make that you then go on adventures on with, with those adventures being controled by someone who is refered to as the dungeon master or DM that is the most surface level way to explain what dnd is. A decent resource to view the useable player content for free would be dnd wikidot
Another great aspect about dnd that I like is how easy it is to add your own content in the form of homebrew, which is the content made my people outside of the company that makes dnd. I even have my own set of homebrew things, namely a few subclasses and an item, if you are interested you can find my homebrew here (do note that any mention of a pateron or extra content or anything like that is not real as I added that for a school assignment that I was doing last term)
*This is just am image of what a dnd game CAN look like, they can also just be online on a site like roll 20 and discord, or something else entirely.
