Pokemon games, fundamentally, aren't difficult, never have been, and never will be.
Post about Platinum or Alola coverage all you want, you always get plenty of opportunities to train, get TMs and X Items, and catch the best Pokemon to destroy the endgame with.
Difficulty in this series has always been self-made, and some titles just make you work more or less hard for it, but at its core, it can't be truly difficult.
