I'm playing Black 2 a bit right now and it's not bad, though they need to change the format a whole lot more than this (especially storyline wise) if Gamefreak wants people to keep playing.
I thought it was a given that they'd release a truly 3D Pokemon RPG at some point during the N64 lifecycle. When it didn't happen, I was surprised. Since it still hasn't happened a decade later, I'm even more surprised.
So, anybody give this a try yet? Even if it's not official and not done yet, an MMO pokemon seems to be the next-best thing to a full-blown 3D one.
