One of the defining reasons I loved Black and White so much was that it was basically a fresh start. 150 NEW Pokemon, all new, no crossovers or repeats until you beat the game and unlocked the endgame content. I was able to get all 150, making me feel fantastic, until I finished the game and remembered I still had like 400+ left to get, then I just gave up.
Black and White 2 were a little bit confusing thanks in part to the fact that it was the 150 from Black and White with 150 more, making the game START with 150; it also took some of the challenge out by giving you Growlithe and Riolu super early in the game (levels 11 and 5, respectively), and that made huntung for an ideal team pretty easy since Arcanine is one of the best fire pokemon in the game (double so once he gets Flamethrower), and Lucario remains my single favorite pokemon to date.
My Black/White and Black/White 2 teams were VERY different. I had Eelektross (or whatever his final evolution was) as my electric type in the first game since he had levitate and therefore had NO weaknesses, but I'm using the fully evolved MAgnezone in Black and White 2, and even though he has a great type mix and fantastic stats, I'm not finding him all that useful. I'm noticing a lot of what's going on in black and White 2 remains useless by comparison, and I don't know why.
X and Y being new pokemon games really could open up a world of opportunities, but I figure this will just be the same old same old. I love the same old same old, but I'd love to really see them overhaul it. We just had 9 goddamn pokemon games on the DS, I think it's time we moved on. (Diamond, Pearl, Platinum, HEartGold, SoulSilver, Black, White, Black 2, White 2).
