As gamers, we have put in an obscene amount of time into our hobby. Personally I find that not only do I remember these games, but what really has an emotional response are the things I've add to the games myself.
What kind of things you may be asking? Well, take that gif up there. I wrote a post about the very first time I played a video game. In it I talked about vine dancing in Mario and how that was what drew me to the game. Such a simple thing, and really who knows if Mario was supposed to be shaking it on top of a vine or not. Well, GBD might, but what mattered to me is that he did dance and it's engrained in my memory forever.
