Music for sure, I find myself humming themes from Wind Waker and Mario 64 and Galaxy and Super Smash and even Mario Kart all the time.. For me they are the what brings back the greatest nostalgic memories.. especially some of the music in Galaxy.. reminding me of past Mario games.. I loved it :D
I really never think of the graphics when i think back to a game, I think about the feelings I had towards the game and the music helps with those feeling.. Windwaker, the music making you feel lost at sea or on a grand adventure and Ocarina of time as well.. I can't even remember what Banjo Kazooie was really about but I remember the music and the feelings I had playing the game..
