I still get a kick out of looking through the Prima strategy guide for Destint 1. The pages where it explains light level, mechanics, economies, etc. It's actually kinda funny to see the vanilla stuff that became obsolete so quick. It's not about it being useful, but about it being entertaining. I preordered the grimoire book, and it'll go next to a bunch of other collectible books that I have, and from time to time I'll thumb through them and enjoy the retrospective, nostalgia, and to me that's worth the money.
