Briefly put, this is a great idea, badly realised.
Not even close to being comprehensive, this book is missing many, many characters, even including ones from Street Fighter (T Hawk, Dee Jay, Hakan for example. No C. Viper? Realy?)
It also has a habit of featuring some characters from a franchise but not others (A few from Rival Schools, but over half the RS roster missing)
The book also has grammatical and factual errors, which is a shame.
A fine book for the collection to buy on the cheap and flick through, but not even *close* to an "encyclopedia" Comes across more like an unofficial fan-book.
Maybe an updated edition will be released sometime, after all, when it comes to regular updates, who beats Capcom?
