Most of our older members have disappeared. I remember when I first joined several years ago, I felt like I was a young'un compared to most of the regulars (I was in my early 20s back then). Now I'm 30 and I feel as if I'm among the oldest members, although apparently I'm not out of those who have posted in this topic.
I remember back when I first joined there were a lot of regulars who were still very big on playing and collecting pre-crash consoles, but I guess as those people left, yeah, NES is about as early as most of our current regulars go. I have to admit that I'm included in that, seeing as I own and play very little of systems that came before the NES.
