Having the game revolve around an entirely new Pokedex (at least before post-game) was the smartest thing Game Freak ever did. It also helps that the story’s actually engaging this time around, but also Unova is one of the best regions in the series. It’s a little, I dunno, darker? More… real feeling? I’m not sure how to articulate how I feel about Unova but man. Gen V is so good
