Final fantasy 7, Donkey Kong 64, Goldeneye 007, Final Fantasy 10, Tony Hawk Pro Skater 1, Digimon World all bring a nostalgia factor. But probably, final fantasy 7 brings the most nostalgia. I have played that game again every 3-4 years since I was 12.

Not really, i grew up in the AOL era, so for me it was chat rooms, and sometimes (but not often) actual forums. Then it was myspace after that.
