Never played Dead Space, but you're right, parasites are featured there as well :D

Ever - I think that's great for the Jack arc. But yeah, if Nobunaga ends up only with Arrancar, that's going to be a lot like Aizen, although thinking about Nobunaga, he somehow seems much more bad-ass than Aizen.

Otherwise, I like it.

EDIT: Also, as we sort just those few details out, I'll be making an OOC - and also, I was thinking of putting no limit to the number of characters one can control. Unless you guys have a problem with that? I've been in a few RP's that limited it to one character and it ended up having very few PC's.
