I think one of the reasons this game manages to stand the test of time so well, at least for me, is its message. It's one that constantly changes and evolves with you the older you get. So many people have talked about this already, so I won't parrot what they've said, but I can't think of any game or even piece of media has managed to share this specific message and pull it off nearly as well, with such rich subtext too. I'm the same age as this game and it's one I still think about often, especially as I get older.
