limbo
the most unique and gorgeous visual design this generation. absolutely stellar, unparalleled audio design full of organic noises, crystal clear nature sounds and hints of gloomy strings and harmonies, all seemingly emerging from the same otherworldly static. an atmosphere of both dread and beauty, of quiet and somber awe, chillingly intimate yet filled with echoes of a distant, enigmatic darkness; a sense of place quite unlike anything else out there. no text, no hud, no explanations. nothing between the player and the world. everything slowly fading in. everything slowly fading out.
i can't think of another world in any game this generation that captured me like this and never let go.
