All in all, A great resource and product.
The Chronodex is as wonderful as the name is memorable. Each of the sections are organized in a way that one can remove or add additional copies of any section they need. Have an army of unique NPCs? Jus print off more pages. Rather not chart the different regions of your game world? Just switch them out.
The Chronodex also reintroduces some quirky video game aspects that are more for fun and interest. I never thought I'd like to know what my character's official killl count was until I saw the section waiting for my tally marks. And the idea of "Achievements" that the players and characters can earn is a fun idea, regardless of whether you award such meta-behavior.
As I said before, this is a great resource for those who want to be a bit more organized. Or a great treat for the party note-taker, lore-keeper, and general purveyor of important details.
