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.

Call Of Duty: Modern Warfare 2 Hhahahhaha
Pretty young so my childhood was not too long ago.

Zelda on the good old NES, nothing beats that classic old game.

Would probably be the first LEGO Star Wars or something

Command and Conquer, Red Alert. It is an old game made in the late 90s that never gets old

Old School Runescape most definitely. Came home every day from school questing and grinding my account out only to be let down once EOC came out.

Not that old, but DIGIMON MASTERS ONLINE...
Being in love with DIGIMON since ever :D

Super Mario Bros 3 for me. I remember playing it on the NES as a little kid. Good times!

Quest for Glory series gets me every time, especially 1, 2 & 3 as they were all I had for the longest time. That and Police Quest 2. While I had some other games, I was largely a Sierra child.

Pokemon games on Gameboy lol. Just growing up i played 5 generations of it and then i got into PC gaming that would bring me to Starcraft, Warcraft, Diablo, and Counterstrike as my most nostalgic game. My friends and i would just go to Internet cafe and play for hours.
