The Capcom 30th Anniversary Character Encyclopedia, agorgeous compilation of over 200 pages of Capcom art, was available at New York Comic-Con for over $20 earlier this year, but now you can snag a copy for a little over $10 on Amazon. Joystiq swears that the price of $16.99 as reported on Capcom Unity's blog doesn't matter; it's still only $10.39.
Authored by BradyGamers, it will of course cover the likes of Mega Man, Resident Evil, and Street Fighter, but like any good encyclopedia, will have plenty of obscure characters for the hardcore Capcom fan. (I wonder if they'll allow Marvel characters in there...)
This hardcover book weighs 1.4 pounds, so you may not want to use it as a coffee table book, unless you're like me and just don't care.
