I don't know what everyone is talking about, dark souls is not that hard. I'm on my fifth play through the second one. On Skyrim I had a overpowered knight so I had to switch to legendary to not one hit enemies. Legendary on the past 4 halo titles seemed dumbed down when you play it alone so it wasn't that challenging, although halo 2's legendary was insanely hard. I didn't beat it though. I would say halo 2 on legendary or AC4 doing tailing sequences or legendary ships.
