lol! My roommate hates the story but loves the games (he's dubbed me as his story explainer), while I love both the games and the story. Sometimes I'm not too thrilled about the milking of the series (see: RE:coded), while other times I'm all for trying something new (see: original CoM <3).

I would say more curious than the weapons would be the elements. Each of the organization members was associated with some sort of element (with time, etc. being abstract ones, but "elements" nonetheless). But yeah, back story on the organization would be appreciated. Also, No Heart + Terranort connection would be interesting to learn more about. In the kh2fm+ vid, Xehanort (which is terranort's nobody at this point if my understanding is correct) is in possession of some armor seated in a chair. Its been a while since I've seen the armor, so I can't remember if it resembles Aqua's armor or No Heart more. Since aqua's armor was found with terranort post last episode, it would fit, but at the same time, in the final boss sequence in kh2, the armored guy in the chair is definitely wearing the no heart armor.
