probably gonna turn this into a longer post later but a correlation I think should exist in ttrpgs is that likelihood of death should directly relate to the ease/fun of your character creation system.
if it takes me an hour to build a new guy then you should provide safety nets- death saves, what have you.
if i can roll up someone new in 2 minutes and wind up with a new little freak than you i should be able to die with one bad throw of the dice.
