The original generation five Pokémon games are already some of my favorite games in the Pokémon series, yet Pokémon White 2 manages to knock it out of the park as one of the greatest sequels to any game I've ever played. Not only does it keep many of the original game's strongest traits, like the sprite work, characters, and soundtrack, it also expands upon the original experience. The Unova regional Pokedex is expanded to include many old fan favorites to go along with the Unova Pokémon from the first game, making this one of the best selections of Pokémon in the series. The Pokedex isn't the only thing they added, as the world has many new towns, routes, dungeons, and even gym leaders to help expand upon the original region. Add in a solid postgame that includes my favorite Battle facility, the Pokémon World Tournament, and this is easily my favorite entry in the mainline series.
