I hate the fact that it's become difficult to find retro games nowadays, so I just have to rely on getting lucky, like finding The Legend of Zelda: A Link to the Past for 50p at a car boot sale or Um Jammer Lammy for 59p at Cash Converters (I live in the UK by the way). I hope your right about the appeal of retro gaming becoming a fad, in the same way Beanie Babies was a fad.
Great article!
