Woot woot! I just saw this bad-boy from Amazon.com. Yeah, I’m plugging Amazon.
Anyways, you can get the standard edition for $30 on DS or 3DS, and the collector’s edition on either portable system for $40.
The Collector’s Edition comes with a stylus shaped like Finn’s sword, a map of The Land of Ooo, a “premium SteelBook case” (same as the Halo 2 special edition, then adopted by many other special editions), a monster manual, and of course the custom package design is of the Enchiridion.
