Anyone that has played the Wind Waker (G-R-E-A-T game) and gone down all those holes on Outset Island just to see what is at the bottom (not much) will have known they have faced a challenge rarely found in modern games. Dubbed the ‘Savage Labyrinth’ this is my pick for the hardest part in a modern game. It’s long with more difficult enemies. There are no items dropped by enemies, meaning you can’t replenish your health for the entire ordeal. Most importantly if you eventually die you start again from the beginning.
I know that games are getting easier, so much so that now it’s not a matter of if you can beat the game but if you have enough time to beat the game.
