Honestly, any game loved and played to death when we were kids isn't going to hold up as well today. Everything's on a different scale now.
There are some games I've tried going back to and they just don't hold up. I don't feel like doing everything in them because I already did, back when I was in grade school and had mountains of free time. Even a beloved favorite of mine, Zelda: Ocarina of Time, doesn't feel as epic as it once did. It's still fun and a great game, but it's never going to recapture the magic it had when I'd play it again and again during the winter breaks.
