BW was an excellent game. They're tied with Emerald for my favorite games in the series and Unova is my second to Hoenn as my favorite region. Yeah, I love Hoenn. The Pokemon were pretty disgusting, but I still managed to find a good amount that I like. Still, I see many people enjoying the ugly little monstrosities, so maybe I just have high standards when it comes to my Pokemon.
Anyways, whole not being a huge step for the franchise, it certainly improved many aspects. The battle system is obvious, the storyline is longer and more interesting, and there are many interesting characters; complete with Gym Leaders that don't sit in their gyms during the whole games.
Really, the only thing I didn't like was the new Pokemon, but I approve of Game Freak's decision to keep the older ones out of it until post-game. I liked seeing "Youngster Bob sent _______" and not knowing what the heck it was. I had no idea what its type was, what it's ability and moves were, etc.
So yeah, Game Freak dazzles me again.
