I mean, this one needs no big introduction. The fifth generation of Pokémon games may have had its detractors back in the day, but nowadays it's widely acclaimed by most fans and rightly so, because these games are and were always amazing. Black and White 2 is seen by many as the superior entry, thanks to its wider variety of Pokémon to catch, amazing post-game content, and just being an all-around very complete Pokémon experience. Personally, I always preferred the originals as they had a better and more focused storyline, whereas the narrative here in the sequels sacrifices some of that focus for a more "traditional" Pokémon story. It's still one of the best narratives in the series though, not that that's saying much! Anyway, yeah. Great game, one of the best in the series, always fun to replay and randomize.
