I've played several games with harsher punishments, the most recent of which is Diablo IV with its hardcore mode. If you die, the character is gone, start over from level 1 with a new character. That can be days, weeks or even months of work gone. I would not call a wipe in deep dungeons overly punishing, just annoying and I would definitely call deep dungeons having one of the biggest punishments in all of gaming a huge exaggeration. An exaggeration bordering on absurd hyperbole.
