Welcome to KHI! I personally think that KH1 is the best KH so far, but BBS might surpass it, despite being on the PSP. I'm amazed at how much content they could fit it so far. I hope it doesn't disappoint. If don't care about spoilers, remember that Jan. 9 is the day it comes out in Japan, but I'm sure you do, so I'd best advise you to not view the spoiler tags in the Jump Festa thread. In ways, I don't like they seem to be spoiling it, but then again, perhaps for everything they release to the public, there's several more things being left in the dark.
Anyways, enjoy your time here, read the FAQ and stickies (of the various sections, especially FoKH section) when you get the chance. Oh, and please be sure to never post KH threads outside of the KH sections. There's a chance that you'll never hear the end of it, at least until a staff member moves or closes your thread.
