>>29938731This has something to do with it, but I think there's also another thing.
The games are so fucking transparent with you these days. They tell you exactly where you'll go and what you'll find before you're even allowed to take a step. And everything has a clear reason that's thrown right in your face, everything can be boiled down to either "This is ancient Pokemon magic!" or "This is cutting-edge technology!" instead of mysterious events that just exist and let you draw your own conclusions. There are no more secret little rituals like the Mt. Moon Clefairies or the Friday Lapras.
Only thing I can think of in the recent games that comes close would be the Lumiose Ghost Girl. But there's no adventure or special time or anything in order to get to that. No ritual.
