Downloaded this at launch and played through about half of the overworld map before shelving the game for a while due to the grind required to progress. Eventually when I came back, I had a bunch of free packs to download after restarting my game from the beginning and working through the game over a few days. Learning how to play better from those that have finished already and finding shinies made it enjoyable, but in the end, its an isolated Pokémon game that is fun, but not super replayable.
