I played Rogue Legacy and Dead Cells combined at least 150h and only a bit of BOI. I know that in RL the shtick is that with every new run another one of your family is the character. And in Dead Cells you just use a new body every run. The stories in those games aren't very elaborate and the games would just be as good as they are without story.

Hades is different in that the story parts of the game are an important part of the experience (you go around and get to know a lot of different characters and find different ways to upgrade stuff) and that the main character Zagreus doesn't really die - he is also a god. When you lose all hp you just get transported back to Hades and almost everyone there has new tings to say and the relationships develop over time.

I don't know how to explain it better but the main idea of a roguelite is clearly there the execution is way more elaborate and story heavy than RL, DC or BOI. Slay the Spire is on my imaginary backlog of games in need to play before I die.
