I've sunk 80 hours into this game, did all the optional battles, got all pokedex entries perfected, and caught a lot of shinies, basically everything there is to do.
Now, with other new Pokémon games, this is where I'd think "I'll replay it after a week or so", but I've got no intention of returning to this game, it doesn't feel as "replayable", if that makes sense.
I don't dislike it by any means, but I feel like I've had my fill of it for a long, long time. If they release PLA DLC this year, I probably won't play it until after Gen 9 is out.
