Can confirm the difficulty part. Not because I myself was terribly skilled at games when I was a kid (I was very much not, in fact), but because my brother's daughter is, who is like 11. Not only does she make playing Mario Kart 8 almost look like a competitive sport, but also, this is the kind of stuff that she plays on her spare time ever since she was like 6:

Yes, extreme difficulty included, and she makes it look like default difficulty. Meanwhile, I myself cannot even get a damn perfect in Splatoon 2's rhythm minigame for anything beyond literally the easiest 3 songs in the easiest difficulty.

The whole "kids can't do difficulty" is, has been and will remain being the biggest lie in gaming. Kids can be way better¨than any adult not playing competitively on just about any game, and Pokemon in particular has no excuse, since even the hardest of Pokemon games are not that hard.

A concerned fan, which is all it takes for it to be valid input.
