From time to time, I still do, yes. I've really enjoyed playing original Pokémon Black and White, so I decide to give them new runs every once in a while just so I could relive. Currently, I'm on a third White run; so far, it's going phenomenal. My current team consists of Breloom, Metang, Emboar, Staravia, Snorlax, and Gyarados, and these Pokémon are able to perform with each other pretty well. I do have two flying-types here, but that doesn't exactly matter; Metang is able to cover their weaknesses pretty easily, and same goes for Emboar.
As for Black 2 and White 2, I haven't finished either of them yet, sadly, but am trying to get one done bit-by-bit! I'm up to the last gym right now, so have only few other things left to get done before story is officially over. Very excited!
