You can say what you like about Udon Entertainment and their inability to release anything on time, but such sins are usually forgotten when you finally get the end result in your hands. What you'll probably do is turn around and say that you can't rush genius.
What Udon do really well is artwork and what they do even better is video game artwork. Since partnering Capcom with the Street Fighter series, they have gone on to look at other games such as Dark Stalkers and Exalted. Megaman Zero is the latest art book they have released, and it not only does it adhere to their high standards it represents a great art book.
First up it, it is crammed full of great art work covering both major and minor characters and all their costume designs. Secondly they show you how they designed various features on the characters. However the real triumph is that they let the book also tell the games story, providing plot synopsis and full character introductions. This was perhaps missing from their "art of capcom", and hopefully shows that will continue to raise the bar in terms of standards for future art books (the Dark Stalkers Graphic File and Street Fighter Tribute). To round it off, the book has great cover, with a special foil cover, which finishes the book fantastically.
What I would say, is, even if you were not a die-hard fan of mega man, this book is still worth getting, the art work is immense.
This book is fantastic. The picture of the characters in the game is well manage from page to page. There are also a lot of information which link the X series and the Zero series that the game do not really cover and its quite mind blowing (I won't spoil it!). The book also shows a lot of artwork ideas which they later implement in the games, artwork that do not make it into the game, original characters sketches and behind the scenes story, how they got the ideas for the games and stuff. This is a must own book for Megaman fans
