I found "Hardcore" more appropriate; reminds me of Diablo 2's Hardcore mode where your character can't be recovered after any single death. "Nightmare" takes me back to Doom where it was just a harder mode, without the extra "permanent death" rule. Sorry, that's my pedantry out of the way for the morning :)
