A really good time. I've said before that I really enjoy an element of remixing in Pokémon games, playing with established locations and creatures and mechanics, and another part I really value is when the game really leans into its mythos, makes it a big part of the narrative and the region, and this game has both in spades. Not only is it a successful remix of the originals, it also majorly adds upon the story and mechanics of X/Y and really makes it its own, completes it. It opens up in a big way by the end and had me spending a lot more time in it since it's so compelling to see every bit. The new flight mechanics may seem like they create a greater sense of conquering the game world, fitting it into your palm, but instead I found it made the world feel bigger, full of possibilities and secrets. It's essentially that feeling that makes it so great.
