Nethack is one of the defining roguelikes. I talk a bit about what it is really about from a subjective experience and compare it a bit to Hades, one the current roguelike poster-children.
One of the differences, which I think is very important, is how they represent progress between runs: Nethack doesn’t represent it at all, whereas Hades has both upgrades for your character as well as narrative elements that get elaborated as you play the game.
