We all know that some strategy guides are better than others. Some are full of errors, others are poorly organized or missing vital information, while others are downright useless. Of course, my favorite strategy guides are a treasure trove of gorgeous artwork, comprehensive walkthroughs, maps, checklists, character bios, achievement/trophy strategies, etc-- books that are really worth owning and offer an experience superior to GameFAQs and forums. What are some of your favorite strategy guides? Here's one of mine:

I was really surprised by this one. A labor of love from authors who clearly love Castlevania, this guide covers everything you'd ever want to know about Castlevania 64, and then some. The last 8 pages are a feature on the "History of Castlevania", with screenshots from each title and an opinionated write-up on what works and what doesn't, and how each game fits in with the overall series. This is one guide that was written by fans, for fans.
