I was not involved with the C64 scene but personally I had a great time playing games on it. In fact C64 emulators are probably my most played, VICEX on my xbox is the main one that jumps to mind. The way all the games are categorized and you can play the music files with a click of a button is pretty damn nice. A similar thing for snes emu's would be cool I guess.
The games I remember most? hmm
Stop The Express Summer Games Winter Games It's A Knockout The Last Ninja series Rick Dangerous IKARI Warriors
Man there were some treats back then. I'd like to know what I know now and relive my childhood again although I would probably be dead by 16 through lack of sleep haha.
