Pokémon Black 2 and White 2 were the second games of Generation V, released in Japan on 23rd June 2012, North America on 7th October 2012, Australia on 11th October 2012, Europe on 12th October 2012, and South Korea on 8th November 2012. The “extended” commercial only shows gameplay, which was significantly enhanced compared to Black and White and offered new legendaries in the form of Kyurem (White or Black).
Compared to Black and White, I loved Black 2 and White 2. I owned Black 2 and loved the fact that I could get Pokémon from previous gens (most notably, Growlithe, a Pokémon I never had access to having always played Blue). It also felt more developed and was generally fun to play.
