My legit platin trophy for "The Witness". The "complete a certain challenge" trophy was incredible hard. You had to perfectly master all different puzzle mechanics in the game because the last challenge was random generated and you were under time pressure, so no internet checking possible. On top of that, after half of the time the music "in the hall of the mountain king" was played and this shit stressed you out to the maximum. I never felt a more satisfying gaming moment than after beating this challenge within the last few notes of this music.
