My first system was a Sega Genesis, and I loved playing the Sonic series (minus spinball and 3-D, but I still got em') and other classics(SOR,SOR2,SOR3,Spiderman/Xmen,Xmen2, which is still my current fave, and most importantly: Maximum Carnage.) These games are all good and that's what made the system good to me is it's games. I liked the SNES too(for RPG reasons) but the one I was raised on (and still play today, burned songs from Sonichq.org) and still have fond memories of today is the Genesis, the only system I don't have that is Sega related is the Saturn and that is because I cannot find one,(but I will, take my word for it)so dust off that game, and play it and take a trip down memory lane cause I know I do. And you old-schoolers know no game will give you the replay value and enjoyment of a classic system like the feeling you had when Aeris died, or the  first time you beat Robotnik, these game have a value that no other can match so when you find the time to play these, do so cause in the end, these new systems may have graphics and fancy stuff, but one thing they will never have is the feeling of enertainment and gratification of a job well done. Most newer titles can be beaten in a day (some even less than that) but I dare you to play Super Mario World and try to say you can beat it in a day. That's classic gaming for ya.
