Well, I had an idea of how BBS 2 Would kinda go, it would go like this, remember this is only an idea.
BBS- Storyline about worlds being swallowed up in the darkness, possibly Ven could comeback maybe!
Possible that we would see what happens to the Organization 13 Members somebodies and some other members somebodies like larxene.
Hopefully many new worlds, new keyblades, and maybe a new battle system. Another secret ending of course
For worlds am not really sure.
BBS 2 Could have multiplayer again, possibly even a CO-OP For the storyline like 358/2days mission mode, Heck it could even be released on the PS3 And PSP (Maybe).
New heartless bosses, we would have not a new villain or could have one, maybe more insight on MF (Mysterious Figure) etc. like who he is, his background/origin etc. Soo yeah that's what i have so far, Hehe just imagine if some of what i said was actually Accurate!
