I think that's just experience. You grow old, you read and you get used to things. You start to accept them as the norm.

I can dig the return to the roots of stories you've heard. Looking at the myths beneath the fantasy adaptations, and in turn the adaptations of those myths. Glorantha is a great example, and i think stuff like gilgamesh and Cid and the odyssey is magic in its own right. These stories are very visceral and feel deep with age.

BUT we don't have to discard the stories we make up, experience and bad eon other deeper things with stronger meaning. Glorantha is every bit as valid as the myths that have spawned it, imo. If a story is cherished and brings emotion and wonder and karthasis and stuff (what a story should bring is a question for the poetics lol) to a person's life, it fulfills it's purpose

Also, edit: while I notice that generic fantasy speaaks to me less with the years, presumably as I know the tropes more and more, it still speaks to me more than other genres. I'll take bog standard dnd over real-history fiction about court intrigue and romance in feudal England, for example.
