A 2.5 guide would be excellent to have. Not so much for KH 2, but more for Birth by Sleep and the commands.
Don't forget about how beautiful the 2 books would look side by side on your book shelf or living room table. Take about a beautiful collector's piece
So the guide uses Xemnas to identify the Hollow Bastion secret boss. That was what I would
I agree, it's a spoiler, BUT, I'm not against it. Xemans is in both Re:CoM (as a card) and in Days, where in the opening cinematic you can SEE him using ethereal blades. While I understand that it's a spoiler to some, who honestly cares? Him being in KH1 is just as big as LS was in KH2, not really important. All they do is hint at the next game but they do not affect or spoil anything huge in the storyline one way or the other. Also, if the person has never played KH before, they won't know who "Xemnas" really is, so he'll just be a name in the wind.
If anything, it'll lead to an "A HA!" moment when they see him in Days and realize who he was (since I'm assuming some people won't connect the dots).
Anyway, the book is flawed and the layout is somewhat dull. I'll just leave it at that.
No guide is perfect and I agree that the inside is dull, but I still think it's definitely one of the best KH guide books to come out (not the best, I still leave that to the main KH1 guide) but really nice and on the better half (way better than DDD -__-)...
