I want my characters to die. I didn't realize until recently how alone I am in this, but the idea of playing a campaign almost more like a roguelite (or maybe a Pokémon nuzlock?) is so appealing to me. I want the consequences to be so real that a decent player might need 2 or 3 backup characters, where a happy ending isn't garunteed in the slightest and the DM is fine to end the campaign in total tragedy. then the victories and successes would feel so much more earned, and campaigns would feel much less like on-rails experiences. plus failures can encourage creativity. a story where everyone just wins each task after the other is boring
