I was recently thinking that Emerald was truly the best Pokémon game. Think about it, just so much exploration to do and the mystery around it made it all the more interesting. The only game where you can have so much to do after you finish the game with the best Battle Frontier, the mysterious Regi puzzles, Latios hunt, Kyogre and Groudon hunts, getting to the Sky Pillar. Just an overall magnificent game.
