Crisis Core Ultimania
Got this in the mail today. I didn't know it was going to be hard cover! Content-wise it's quite similar to FFVII Ultimania Omega: story digest, battle strategy, concept art (very small volume), etc. The one feature that made it much more valuable than most Ultimania books would be the complete script collection + BGM descriptions. Sure, Crisis Core is a short game that can be beaten in less than 24 hours (if you ignore all the missions), but it's still a lot of effort to capture every scene and record every single word. I also enjoyed the storyboard section a great deal (plus the funny side notes from CC producers), and you get a special bookmark as a part of your order.
