I'll be honest, I'm astonished they didn't simply put out Grey. Either way, I'm pretty hyped for this and I'm really hoping these two games improve B/W like Emerald and Platinum did with their respective generations. God knows B/W need improvement where post-game content and online options are concerned, at the very least.
Basically everything and a half was leaked today. Right down to returning Gym Leaders/E4/Champ/"guest" battles, certain Legendaries/story elements, Move Tutors, Wild Pokemon, and the rumor of a way to change the difficulty of the AI post-game. I'm actually weirded out by some of the changes, but still mostly hyped.
This game is really good, definitely improved on a lot of what the original Black and White lacked. There's a lot more substance to the towns and cities, and there are some places like Driftveil that have drastically improved. Oh yeah, did I mention there's actual post-game content now? Fantastic.
One thing I liked about B/W, though, was that they only let you capture Unova Pokemon until you beat the E4. B/W2 obviously tossed that out the window, but I think it honestly increased the diversity a lot more, and half my team at the end was still 5th Gen Pokes.
For me, B/W2 definitely made this generation a lot better. While mechanics obviously aren't really different, Gamefreak did a fantastic job on improving the little things that held B/W back (Except for re-adding auto-100 online battles...Jesus **** Christ Gamefreak) and adding a lot of stuff that makes replaying this game actually worth it.
Anyways, I'd probably give it an 8.5/10. I dunno if Gamefreak'll ever make a masterpiece like Platinum again, but they're definitely finding the right tools to do so.
Oh yeah, here's my team that beat the Pokemon League:
just about to start Elesa's gym. got a DW Snover and Druddigon, ya? levels 22-25, a bit underleveled but like Log said the level differences are huge.. I also got about 5 shuckle and 7 riolu from Dream Radar
edit: also got DR Tornadus on monday, apparently I almost have enough orbs now to get landorus.. coolbeans
I got a DW Stunfisk and Sandshrew so far. My computer lagged or else I'd have a 3rd by now. I barely beat Cheren due to being underleveled/not using Genesect or trading anything in. You pretty much have to grind your ass off this time around, a few Audino isn't going to cut it.
