...and I already own the Limited Edition hardcover "vanilla" strategy guide from back in November. David Hodgson is the best guide-writer working today, period, and if the Oblivion GOTY guide is any indicator, this one will probably be increasing in value after publication, as well.
Besides, it's a Bethesda RPG. You need a reliable guide, considering how huge their games are, even with all the "free" online strategy guides out there. And again -- Hodgson's work is always worth the price.
