How and when did you first learn about IVs, EVs, Egg Moves, beneficial Natures, and things like that? I'd guess that most people who play don't know what they are, and a chunk that do know don't care.

For me, I naturally caught Pokerus on Soul Silver while training on Mt Silver. I googled what it did, which lead to googling EVs, and it all snowballed from there.

I still remember thinking I was hot shit for leveling a full box of random wild-caught Pokemon to 50 in Ruby, and then realizing how worthless they all were.
