There is one sure way to kill that nostalgic memory of a wonderful childhood experience, revisit it many years later.
Every time I've revisited a classic game that I loved as a kid, all it does is make me aware of how far things have come and how shallow games actually were back then. I have learnt that to keep some memories special its better to not go back there.
I wonder how many people will spoil their rose tinted memories with one of these? Especially when you can just as easily ruin your childhood memories with a raspberry pi or even your phone these days (as long as you still own the tapes/disks of course).
