I was just reading and article about Konami's upcoming classics collection. The article referred to Castlevania II: Simon's Quest as infamous.

It was like a record skip, to me that's one of the best ones. SotN, Simon's Quest, Dracula's Curse, if those were the only Castlevania games I'd have said the series was flawless.

What games did you love growing up, that now you've discovered weren't nearly as popular as you believed.
