I also feel this way about intentionally obscure game mechanics that aren't meant to be fully understood and just meant to be experienced. For Pokemon, it's very easy now to go online and find the exact formula for how exp gain works and all the ins and outs of manipulating your stats, right? But the game never explains that stuff. You're not really meant to know it, the way it was designed.

In the very first games, NPCs tell you that "a Pokémon that you lovingly trained will always be stronger than a Pokémon of the same species that you just caught at the same level", and that struck me so much as a child. And it was true!!
Years later I found out about EVs... both validating and a bit sad to see that lovely sentiment broken down into numbers...
