Pokemon should have more direct sequels! It's been a while since I last played BW1, but I still remembered enough about Unova in those games to really enjoy spotting all of the changes made in BW2.
For me, the most important part of a Pokemon game is the Pokemon themselves, and BW2 having one of my favorite regional Pokedexes is enough to make it a good game on its own. Additionally, Hugh is a great rival and I really enjoyed how Team Plasma was handled in this game.
I think I still prefer the story of BW1 (again, it has been a while though!) and I definitely get tired of Pokemon battles way faster than I did as a kid, or else I would have enjoyed this game a bit more. Still a great experience!
