what old video games give you the most nostalgia?

Best sense of nostalgia I got was from Metal Gear Solid 4 but not because of that game in particular but because of Metal Gear Solid 1. Returning to Shadow Moses Island and just walking around to the places where you've been in MGS1 really grants that big sense of nostalgia. You see that time has stripped away the island and no longer is there anyone alive or any nuclear materials remaining. It's just dead and replaced by the metal gear Gekko. Even as I'm typing it I'm mentally going through that segment of the game and just going wow while nostalgia washes over me.
