Growing up:
>SH games are super popular, and they kept getting better and better, but mean old Konami decided to cancel the series and disband the team for seemingly no reason.

So I've since learned this narrative by SH fans is false, and that after a surprise smash success of the first game, subsequent games weren't as popular or as financially successful. I'm curious about sources and information relating to sources discussing the rise and subsequent fall of the series.

Konami, unlike Capcom, doesn't have a site listing the sales of their major games, which complicates things.
