Nintendo did many things to mark the 30th anniversary of Super Mario Bros., but there's been one you couldn't usually get your hands on unless you lived in Japan: the Super Mario Bros. Encyclopedia. You'll be glad to hear that it's coming to the West, though. Dark Horse Publishing has announced that the official guide to Mario's universe will be available in a standard edition in the US on October 23rd for $40.

Considering my newly found Nintendo fanboy-ism, I’m going to have to pick it up.

It’s up for pre-order now on Amazon.

As are those three Zelda books I’ve neglected to buy. [1] [2] [3]. To the wishlist!
