I'm 30 as well, and when I was a kid me and my brother watched and were engaged with those old tapes as much, if not more than we were the current product. It played a big part of me becoming a loyal WCW guy during the MNW, getting a 2nd chance to experience Hogan and all those guys live.
I think as history plays out, WWE in the late 80's-early 90's will be remembered as fondly as the Rock-n-Wrestling period that came before.
