I need some kind of vaguely achievable goal to keep playing a game, and Hades delivers on that with both story bits and increased/varied difficulty modifiers, where other rogue-likes would go stale much sooner. Having the entire playthrough backed by so many unique characters and a simple set of goals made me enjoy it a lot.

As with similar games, every new run is basically a gamble for getting good and synergizing items, though this didn't really become too much of an issue until much later in the game for me.
