Awesome.
The best artbook I have ever bought...

Conceptual art,
Illustrated back-story,
Alternate angles of almost all the bosses, characters and enemies.
A chart that shows every characters relationship to every other character.
Big 8 page interview with the creators
Alternate box art and logos
Endings to all 4 games
Idiom dictionary
Detailed pics of all weapons and items.
Printed on high quality paper.

BTW it’s all in Japanese. But don’t let that stop you as it is awesome just too look at the great illustrations and sketches that cover this wonderful 176 page artbook.

Excellent.
This is a beautiful volume collecting all of the illustrations of the Rockman Zero series. Most of it is full color, and there is an entire section showing concept art-- not only for the character designs, but as an unexpected bonus the early designs for the logo are given as well. Be aware that this book contains only art for Rockman Zero, not for Zero's appearances in the Rockman X series. I wasn't expecting this, but I can imagine that some people would. Highly recommended!
