I don't disagree. I think the way a newer player (by which I mean someone in their first three or four playthroughs maybe) perceives them, from hardest to easiest, is: Tomb of the Giants - You can't see anything and every enemy kills you instantly, so this is obviously the hardest! New Londo Ruins - The ghosts come from every whichaway, it's hard to find your way around, and you're constantly surrounded by baddies! The Duke's Archives - Most of the enemies are weak, so this one isn't as bad as those two. Lost Izalith - Not a lot of enemies, pretty straightforward run to the frustrating boss. And for a very experienced player, I'd say it's more like: The Duke's Archives - You have to fight stuff that hits harder than what you have to fight in any of the other three, and there are projectiles coming at you at all times. New Londo Ruins - Not that bad since you know the downstairs pretty well and know how to skip the middle part. Lost Izalith - Not a lot of enemies, pretty straightforward run to the frustrating boss. Tomb of the Giants - Darkness presents very little difficulty because you come prepared and know your way around by now, also all of the enemies in the dark part are optional and all of the ones after that are easy. It's actually kind of cool and amazing how comfortable you eventually get with the Tomb, since it represents nothing but terror and frustration when you first encounter it.
