Gta V, and Uncharted/last of us. Sure those last ones it's mostly graphics, but it was impossible for a game in the 6th gen to have such a immersive atmosphere.

Wind Waker is the single most charming game I've ever played and one of my favourite games of all time (top two/three). The fact I can say another game of its gen, Metroid Prime, has an even more immersive atmosphere says everything in my books.
