Cyclone appears!
Messaging as I said I would.
I actually find Black 2/White 2 to be a huge improvement. I wasn't a fan of the Cold Storage area, which to me seemed like a quick put-together to create a plot point; I'm somewhat glad the area is gone (and the PWT is there now!). The storyline surrounding Route 10/Victory Road is interesting with R10 being fenced off in Opelucid City (I have also seen what it looks like standing where the gatehouse is thanks to Youtube and someone walking through the fence). And Challenger's Cave also caved in; big deal, it was post-game and again seems like a quick add to an otherwise boring area. I also like the new hometown, which seems to be a response to the many hacks here that also create big starting towns (I'm playing one right now, a beta of Shining Opal).
B2/W2 also gives you older Pokémon in the Unova region immediately; Riolu, in fact (see Lucario), is available at Level FIVE, making it obvious that they are native to the Unova region as they are the only games where they've been found in the wild (Safari Zone doesn't count and even the Bulbapedia article says they were imported to HG/SS now, which I believe). In short, don't hesitate about B2/W2 when the English version comes out; go buy it. I will. It's the first sequel, and some of the changes (Meteors on Route 6 or something, sewers of Caetelia City, actually using that plane in Mistralton City) are very nice and worth playing. I just wish the plane could be upgraded post-E4 to visit Kanto or Johto again, making either Pallet or New Bark Town (or somewhere completely random, making the old hometown a new Gym) the player's home. Maybe in the next game; they may have done this in between to get people to buy this, then people will want the next. Very smart of them if so.
