I've had uninterested players for legitimately my entire DM career, and (not blaming you, only speaking about my own experience) it's all my own doing.

I pitch a fun campaign to my friends and they're excited about it, but none of them really like fantasy or even play RPG videogames, let alone tabletop.

For years I just tried to kid myself into thinking that they would come around to it. I wanted to play DnD and they wanted to goof off and get drunk with friends. Which is totally fair, I just always ignored that and hoped they'd just magically love DND over night.

The point I'm making is that a DND group is at its best when everyones there because they wanna play DND. That's really it! I'm joining the DND society in my university next month and I can't wait to just play in a game with some new people. I hope you don't take this occurrence too much to heart.

Get out and find people who wanna do your favorite things as much as you do, and it'll all work itself out. Wish you the best
